Problems with increasing heavy metal contents in natural waters are becoming a global issue. At the same time, improved methods for water treatment increasingly important. In this context, zeolites can be used to purify polluted water. paper, we investigated how adsorption capacity of improved. Natural from Shankanay district, Almaty, Kazakhstan, were as adsorbent material experiments on improving metals. We found that metals was increased greatly by thermal activation using furnace...
In this study, we systematically study the efficient production method and electrochemical characteristics of activated carbons (AC) derived from rice husk (RH) walnut shell (WS). particular, effectiveness physical activation using carbon dioxide (CO2) was investigated compared with more common chemical potassium hydroxide (KOH). The results show that KOH–activated samples have remarkable specific capacities, reaching 157.8 F g−1 for RH 152 WS at 1 A g−1. However, rate capability AC obtained...
In recent years, the interest of researchers in developing materials that can solve problems energy scarcity and environmental pollution has led to a special focus on nanocellulose carbon nanotube-based composites. Nanocellulose outstanding characteristics promote highly ordered structures are renewable biodegradable. Carbon nanotubes, turn, have high surface area, strength electrical functionality. Their combined use holds promise for development composites with unique properties applicable...
Biomass-based carbon nanofibers (CNF) were synthesized using lignin extracted from sawdust and polyacrylonitrile (PAN) (30:70) with the help of electrospinning method subsequent stabilization at 220 °C carbonization 800, 900, 1000 °C. The CNFs studied by scanning electron microscopy, energy-dispersive X-ray analysis, Raman spectroscopy, Brunauer-Emmett-Teller method. temperature effect shows that CNF carbonized 800 has excellent stability different current densities high capacitance. in...
Inexpensive and efficient desalination is becoming increasingly important due to dwindling freshwater resources in view of climate change population increase. Improving techniques brackish water using graphene-based materials has the possibility revolutionize production treatment. At same time, graphene matter can be cheaply mass-produced from biowaste materials. In this, material was obtained a four-step approach starting rice husk (RH), including pre-carbonation, desilication, chemical...
The use of enterosorbents-materials which can be administered orally and eliminate toxic substances from the gastrointestinal tract (GIT) by sorption-offers an attractive complementary protection humans against acute chronic poisoning. In this study, we report results developing a microgranulated binary biomedical preparation for oral use. It was designed with core-shell structure based on pectin low degree esterification as core, nanoporous activated carbon produced rice husk, AC-RH, shell,...
After undergoing biological treatment, wastewater still contains substances with endotoxic activity, such as lipopolysaccharide. However, due to the increasing practice of treating make it suitable for drinking (potable reuse), removal these active materials is crucial. These can be harmful human health, leading a condition called endotoxaemia. Furthermore, environmental endotoxins pose risks pharmaceutical manufacturing processes and quality final products. Ultimately, most significant...
Представлены результаты исследований, проведенных в Институте проблем горения (Алматы, Казахстан), по синтезу наноуглеродных материалов и их применению экологических целях. Разработаны методики получения из рисовой шелухи скорлупы грецкого ореха (графенов активированного угля соответственно), изучены физико-химические свойства возможность практического использования синтезированных материалов. Исследования графенов методами инфракрасной спектроскопии комбинационного рассеяния позволили...
SrTiO3-based photocatalysts have become widely used due to their excellent properties such as high thermal stability, photocorrosion resistance, and stable structure that can be modified by doping making composites. In this work, SrTiO3 powder was prepared from Sr(NO3)2 TiO2 precursors a simple chemical precipitation method followed calcination. It determined calcination at 900 °C treatment in nitric acid solution produced cubic particles without the presence of any impurities. addition,...
In this paper methods for obtaining graphene oxide from rice husk were developed, which using a downward approach based on four-stage strategy: preliminary carbonization, desilication, activation with KOH, and exfoliation its comparison the method of graphite oxidation. The samples analyzed by elemental analysis, SEM, Raman, TGA FTIR. analysis show that proposed allows to produce materials carbon content around 70% rich in inorganic matter (0–20 wt.%) (K, Fe, Si). To remove contents,...
The review presents data on the nomenclature and production methods of most intensively investigated classes nanoporous carbon materials, which are increasingly used in science, medicine, various fields economy. traditional activated carbons, produced by conventional biomass fossil hydrocarbon processing methods, compared with materials obtained using modern synthetic methods. Recommendations given use template synthesis to obtain a controlled nanoporosity. Self-template synthesis,...
