The efficiency of cationic-based hydrogels in heavy metal removal from wastewater

Bakıt BORKOYEV | Kalıypa SALİYEVA

The present study draws attention to arsenic (V) (As(V)), chromium (III) (Cr(III)), and chromium (VI) (Cr(VI)) heavy metal pollutants, which have negative effects on aquatic ecosystems and indirectly pose a serious threat to the health of living things in the environment. Homopolymer and copolymer hydrogels were synthesized by the UV polymerization technique using 2-acrylamido-2-methyl-1-propansulfonic acid sodium salt (AMPS) and 3-acrlylamidopropil-trimethyl ammonium chloride monomers, and a crosslinker aimed to improve the swelling properties and metal sorption of the prepared hydrogels. The ...More

Investigation of changes in chemical composition and rheological properties of Kyrgyz rice cultivars (Ozgon rice) depending on long-term stack-storage after harvesting

Camilya SMANALİYEVA | Kalıypa SALİYEVA | Bakıt BORKOYEV

The present work investigated the effect of long-term stack-storage after harvesting on selected chemical and rheological properties of Kyrgyz rice cultivars, Ozgon. The performance indicators of in stack-stored Ozgon rice samples after 4, 6, and 12 days was grain size, grain weight, color, moisture, total starch, amylose, protein, fat and ash contents, and mineral composition as well as the rheological properties of rice flour dough. The change of stored rice is caused by the organic modification of the starch structure, decreasing of moisture as well as proteolysis of proteins in the endospe ...More

Ethnopharmacological relevance: In their centuries-old nomadic life, since their livestock was the backbone of their lives, the Kyrgyz people used a variety of wild medicinal plants for ethnoveterinary practices. However, the plants used for the treatment of livestock ailments never have been recorded, except rarely in local publications. In this study, we present the HSHR (homemade single species herbal remedy reports), their methods of preparation and application, and the livestock ailments for which these remedies were used.Aims: The collect data from the five different high-altitude valley ...More

Gülşat MUHAMETJANOVA | Bakıt BORKOYEV | Kalıypa SALİYEVA

The effectiveness of course videos needs to be analysed, and in doing so, it is important to consider the utilisation behaviours and opinions of learners. In this regard, this study was primarily conducted to analyse Kyrgyz learners' utilisation of videos in a general chemistry course provided at the university level. This study was conducted during the 2019-2020 spring term at a state university in the Kyrgyz Republic and was structured using a mixed-method approach. The total number of participants was 105 Kyrgyz learners studying at the undergraduate level. Quantitative data were collected ...More

Physio-Chemical Interactions of Manganese Sulfate/Acetate with Amides in Water

Kalıypa SALİYEVA | Bakıt BORKOYEV | Külümkan SARTOVA

This article is investigating physio-chemical characteristics in manganese sulfate/acetate and amide compounds including thioacetamide, thiocarbamide, thiosemicarbazide in water at 25 °C by isothermal solubility method. System equilibrium was established within 8-10 hours via continuous stirring. For the determination of manganese ion content and nitrogen ions in thiocarbamide, thioacetamide and thiosemicarbazide compounds, trilonometric, Kjeldahl and Duma methods were used.

Heavy Metal Levels and Mineral Nutrient Status of Natural Walnut (Juglans regia L.) Populations in Kyrgyzstan: Nutritional Values of Kernels

Bakıt BORKOYEV | Kalıypa SALİYEVA | Ali Osman SOLAK | İbrahim İlker ÖZYİĞİT

In this study, mineral nutrient and heavy metal (Al, Ca, Cd, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn) contents of the walnut kernels and their co-located soil samples collected from the four different zones of natural walnut forests (Sary-Chelek, Arslanbap, and Kara-Alma in Jalal-Abad Region and Kara-Shoro in Osh Region) in Kyrgyzstan were investigated. The highest concentrations for all elements determined in the soil samples were observed in the Sary-Chelek zone whereas the Arslanbap zone was found to be having the lowest concentrations except Fe and Zn.
