Autor: Askhat Kablanbekov, Svetlana Yefremova, Feruza Berdikulova, Serik Satbaev, Sergey Yermishin, Nurgali Shalabaev, Baimakhan Satbaev, Alma Terlikbayeva, Abdurassul Zharmenov

Publikováno v: Materials, Vol 16, Iss 18, p 6277 (2023)

Adsorption is one of the common stages in the hydrometallurgy of rare metals. Its efficiency is largely determined by the quality of the sorbent used. The purpose of this work was to create an activated sorbent based on rice husk cellulose for the ex

Rice Husk Research: From Environmental Pollutant to a Promising Source of Organo-Mineral Raw Materials

Autor: Baimakhan Satbaev, Svetlana Yefremova, Abdurassul Zharmenov, Askhat Kablanbekov, Sergey Yermishin, Nurgali Shalabaev, Arsen Satbaev, Vitaliy Khen

Publikováno v: Materials, Vol 14, Iss 15, p 4119 (2021)

Rice husk is a large-tonnage waste left from rice production. It is not subject to humification and therefore becomes a serious environmental pollutant. Due to the presence of two essential elements—carbon and silicon—in its composition, rice hus

Autor: Svetlana Yefremova, Alma Terlikbayeva, Abdurassul Zharmenov, Askhat Kablanbekov, Lara Bunchuk, Larissa Kushakova, Viktor Shumskiy, Yurij Sukharnikov, Sergey Yermishin

Publikováno v: Minerals, Vol 10, Iss 6, p 508 (2020)

Coke-based carbon sorbent (CBCS) was produced using special coke fines with the following characteristics: ash, 4.5%; iodine adsorption capacity, 52%; specific surface area, 600 m2 g−1; and total pore volume, 0.4 cm3 g−1. Gold adsorption from rea

Rice Husk Hydrolytic Lignin Transformation in Carbonization Process

Autor: Svetlana Yefremova, Abdurassul Zharmenov, Yurij Sukharnikov, Lara Bunchuk, Askhat Kablanbekov, Kuanish Anarbekov, Tetiana Kulik, Alina Nikolaichuk, Borys Palianytsia

Publikováno v: Molecules, Vol 24, Iss 17, p 3075 (2019)

Lignin processing products have an extensive using range. Because products properties depend on lignin precursor quality it was interesting to study lignin isolated from rice husk being a large tonnage waste of rice production and its structural tran
