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.

Molecular imprinted polymers: important advances in biochemistry, biomedical and biotechnology

Kalıypa SALİYEVA | Bakıt BORKOYEV

Molecularly imprinted polymers (MIPs) are handmade receptors that mimic the binding of natural antibodies. In other words, MIPs can selectively bind to the target molecule and qualify as bio-inspired synthetic materials. Today, MIPs are used extensively and are being developed further for biological applications. High cost and time consuming techniques are compelling factors for the field of biochemistry, biomedicine and biotechnology (3B), and there is an urgent need for an alternative, cheap, easy to produce, fast and effective method in these fields. MIPs stand out as a promising way for th ...More

University learners' utilisation of online videos in a general chemistry course

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.

Activated carbon obtained from the cotton processing wastes

Külümkan SARTOVA | Emil ÖMÜRZAK | Bakıt BORKOYEV

Activated carbon (AC) was obtained from the cotton (Gossypium malvaceae) processing waste materials. The process was carried out by carbonization at 500–800 °C and subsequent activation at 800 °C by water stream. Cotton biomass is a renewable, low-cost alternative source for textile and food products; however, it hasn't been used for manufacturing of an activated carbon by carbonization in a boiling layer method. Characterization of adsorbents by means of Scanning Electronic Microscope and FT-IR showed that high porosity of carbonized products which was achieved and functional groups were form ...More
