Тип записи:Публикация, METHOD OF PRODUCING HUMIC SUBSTANCES FROM LOW-MINERALIZED SULFIDE SILT MUDS (PELOIDS)(2019-01-01) ;Ж. К. Каирбеков ;I.M. Jeldybayeva; ; In this paper is describes a method of producing humic substances from Saki low-mineralized sulfide silt mud. It is shown that the yield of humic substances from therapeutic muds using this method reaches 6-6.5%. Also the initial peloid and humic substances isolated from it were investigated by IR spectroscopic analysis. The nature of the functional groups of substances were determined by the number and position of the peaks in the IR absorption spectra. The suggested method of producing humic products from low-mineralized sulfide silt muds (peloids) makes it possible to obtain purified, therapeutically highly effective, ecologically-economically advantageous products for physical therapy in the conditions of resorts.

Тип записи:Публикация, Physicochemical and Antioxidant Properties of Humic Substances from Coals of the Oy-Karagay and Kiyakty Deposits in the Republic of Kazakhstan(Pleiades Publishing, 2022-12-01) ;Индира Мухаметкеримовна Джелдыбаева ;Ж. К. Каирбеков; ; S.M. SuimbayevaAbstract The results of studies on the physicochemical and antioxidant properties of humic acids (HAs) and hymatomelanic acids (HMAs) from brown coals of deposits in the Republic of Kazakhstan are presented. It was found that the molecular structure of HAs from coals of the Oy-Karagay and Kiyakty deposits has functional groups of carbonyl, hydroxyl, and aliphatic nature as structural elements. The test samples of coals and HAs were characterized by the occurrence of paramagnetic centers (PMCs) with the Lande spectroscopic splitting factor values above 2.00, which indicate the presence of free radicals caused by a strongly delocalized electron cloud in the molecules of coals and HAs. The results of the amperometric determination of the antioxidant properties of HMAs indicated that the HMAs exhibit antioxidant activity, which will allow them to be used as a biologically active additive in the production of pharmaceutical preparations.Цитирования (OpenAlex) 2Цитирования (OpenCitations) 1 - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, Production and optimization of activated carbon from plant waste with high specific surface area for moisture-saving applications in agriculture(2024-10-20) ;Yerlan Doszhanov; ;Karina Saurykova ;Zulkhair Aimukhametovich MansurovIn conditions of water shortage, sustainable agricultural development requires the use of water-saving technologies, including the use of water-retaining substrates based on activated carbon. In this work, the textural and adsorption characteristics of activated carbon obtained from plant waste were studied at different mass ratios of the sorbent and KOH (1:1, 1:2, 1:3 and 1:4). The aim of the study was to determine the optimal activation conditions for creating a material with a high specific surface area and a developed porous structure. The results showed that the largest pore volume (1.6 cm3/g) and a high degree of microporosity are achieved at a ratio of 1:3, which is confirmed by the analysis of pore distribution using the DFT and BJH methods. FTIR spectroscopy revealed the presence of functional groups (O–H, C=O and C–O) that contribute to water conservation. The differential pore volume distribution (dv(r), cm3/Å/g) also demonstrated that at a ratio of sorbent and KOH (1:3), the sample structure optimally combines micropores and mesopores, which increases the adsorption capacity of carbon.Цитирования (OpenAlex) 1
