тяжелый металл -- зерно ячменя -- фитостабилизация -- генотип
Аннотация: Загрязнение среды, особенно химическими веществами, является одним из самых сильных факторов нарушения компонентов биосферы. В настоящее время в биосферу поступает множество загрязнителей. Среди них – значительные тяжелые металлы. Среди химических элементов наиболее токсичными являются тяжелые металлы. Опасность повышения содержания тяжелых металлов в почве и тяжелых металлов в атмосфере связана с активными всасываниями и скоплением растений, которые не только отрицательно влияют на их активные действия, но и угрожают здоровью человека и животных. Опасность металлов заключается в том, что они обладают кумулятивным действием и сохраняют эти токсичные свойства в течение длительного времени. В связи с задачей изучения генофонда культурных растений в условиях техногенного загрязнения было исследование металлостойкости сортов ячменя с целью выявления перспективных форм для выращивания в Восточно-Казахстанском регионе, а также селекционных доноров, собирающих минимальное количество загрязнителей. Полученные результаты позволяют предложить устойчивых к тяжелым металлам доноров, которые могут быть использованы в племенных и генетических исследованиях. Ячмень является концентрированным продуктом для животных, так как состав богат крахмалом и белком. Семена ячменя, наряду с аминокислотами, белок, лизин и триптофан, которые не могут быть заменены другим веществом, сохранены лучше, чем в других культурах. Ячмень по Казахстану занимает второе место после пшеницы. Восточно-Казахстанский регион благоприятен и востребован для выращивания ячменя. Однако поражение сосудов тяжелым металлом повлияло на ввод продукции в действие.

Аннотация: This article discusses the features of the determination of elements in uranium ores of the Shusarysu uranium-ore province by inductively coupled plasma atomic emission spectrometry in comparison with the ore standard of Ore Research & Exploration (Australia). A multi-stage method of sample preparation for measurement is considered. The existing and developed methods for determining the elemental composition of uranium ores are focused, as a rule, on the determination of specific elements using regulated analysis procedures. However, during routine analysis, we need to quickly and efficiently determine a larger list of elements available with one instrumental method. Various methods are used to obtain multielement analysis, among which mass spectrometry and inductively coupled plasma atomic emission analysis are most popular due to their high performance and low detection limits. The listed methods work with solutions, therefore, it is necessary to pay great attention to sample preparation and instrument calibration.

Аннотация: In the course of continuation of scientific research in the development of Kazakhstani technology for the production of trimanganese tetraoxide pigment, there have been proposed new methods of analysis which make it possible to investigate new nanostructural materials sourced from local deposits. The results obtained are of practical importance and serve as the foundation for developing new technologically advanced domestic production of a competitive product that is in demand both on the national and international markets. The available methods are not able to highlight the particularity and diversity of Kazakhstani manganese ores due to the uneven distribution of manganese minerals and host (waste) rock, the quantitative ratio of rock-forming components and their variation instability. Methods of energy-dispersive analysis of manganese ores from Kazakhstani Zhaksylyk and Bogach deposits have been put forward, electronic micrographs, spectrograms of samples, diagrams of normalized distribution of elements on the surface of samples have been obtained and a comparative analysis with raw analogue samples of some foreign manufacturers has been performed.

anticorrosive properties -- electroplating -- surfactants -- thiourea derivatives
Аннотация: For a long time, the use of various surfactants in the composition of simple electrolytes by researchers to improve the quality of metal coatings with cadmium and zinc has been an urgent task.Surfactants contribute to the grinding of the coating structure, the elimination of their porosity and the appearance of anti-corrosion properties of coatings. For example, cadmium electroplated coatings require corrosion resistance, since they are operated in tropical climates, in underground tunnels. Zinc coatings are widely used in building structures and roofing, on electrified railways and high-voltage power lines, in the mining industry and water pipes, as well as for galvanizing the body material in modern all-terrain vehicles to pass in hard-to-reach places without being subjected to corrosion.The object of our research is the process of electrodeposition of cadmium and zinc from simple acidic electrolytes with surfactants, which are thiourea derivatives of dialkyl-phosphorous acids in the current density range of 0.5-3.5 A /dm2, at room temperature. To confirm the quality of the obtained electroplating, we used a JSM-6490LV scanning electron microscope with INSA Energu energy–dispersion microanalysis and HKL-Basicc structural analysis systems with a useful magnification of 300000.

Аннотация: this article analyzes the method of obtaining water-soluble chelated forms of calcium and magnesium humates for use as additives in the cultivation of agricultural crops. Humic substances, in turn, are an environmentally friendly, as well as an affordable type of sorbents. In the near future, humic substances are increasingly used in various sectors of agriculture. They are in the form of soluble humates, with progress being used as stabilizers of clay mixtures, which are used in oil drilling, as well as for the production of dyes for wood species. And very promising is the introduction of humic acids in the form of soluble humates in the rural economy as growth stimulants.

calcium and magnesium humates -- chelate comple -- fertilizer -- crop production
Аннотация: this article analyzes the method of obtaining water-soluble chelated forms of calcium and magnesium humates for use as additives in the cultivation of agricultural crops. Humic substances, in turn, are an environmentally friendly, as well as an affordable type of sorbents. In the near future, humic substances are increasingly used in various sectors of agriculture. They are in the form of soluble humates, with progress being used as stabilizers of clay mixtures, which are used in oil drilling, as well as for the production of dyes for wood species. And very promising is the introduction of humic acids in the form of soluble humates in the rural economy as growth stimulants.

Кл.слова (ненормированные):
bentonite -- montmorillonite -- sorption -- desorption -- degree of sorption -- Mn2 +and V4 +cations
Аннотация: the process of sorption of Mn2 +and V4 +cations by bentonite of the Tagan deposit studied depending on various factors (T, oC; τ, min; S: L ratio; CMnand CV, mg/l). It was found that bentonite exhibits sorption properties with respect to the studied cations in a wide range of pH values (from 1 to 10). The highest degree of their sorption is achieved at the consumption of bentonite 1.5 g per 100 mass. p.of metal-containing solution. The influence of the nature of the cation on the sorption capacity of Tagan bentonite was established. The most intense increase in the degree of sorption of manganese (II) occurs in 15 min with an increase in temperature to 35оС.The highest degree of sorption of V4 +cations is achieved in 60 min at 25°C in weakly concentrated vanadium-containing solutions (50 mg/l V4 +). Bentonite from the Tagandeposit exhibits a lower sorption capacity with respect to V4 +cations as compared to Mn2 +cations, which is due to the nature of the cation.
