This study investigates the sorption of heavy metallic ions (HMIs), specifically lead (Pb2+), copper (Cu2+), iron (Fe3+), nickel (Ni2+) and zinc (Zn2+), by natural zeolite (clinoptilolite). These HMIs are combined in single-, dual-, triple-, and multi-com... see more

The object of research is bentonite clays, the main rock-forming mineral of which is montmorillonite. This natural silicate exhibits sorption capacity for heavy metal ions due to its high cation exchange capacity and specific surface area. One of the most... see more

Polymer-based, highly porous nanocomposites with functionalized ligands attached to the core structure are extremely efficient in the detection, removal and recovery of metals through the process of sorption. Quantum-chemical models could be helpful for s... see more

Development of reliable, environmentally safe and economically advantageous methods of water purification from heavy metals is the primary task for environmental protection. The effectiveness of sorption treatment and additional treatment of natural water... see more

The processes of lead and cadmium ions sorption by modified zeolite of Chankanai deposit were studied. Chitosan was used as a surface modifier due to its properties: nontoxicity, biodegradability and biocompatibility. The adsorption process was carried ou... see more

The sorption of bentonite clay of Tagansky deposits of the East Kazakhstan region of the heavy metals ions (??2+, Pb2+, Cd2+, Zn2+) of mine water Belousov polymetallic Deposit was studiet. It is established  that the use of bentonite clay, pre-treate... see more

The investigations of ferric and hexavalentchromium  ions sorption by yeast cellsRhodotorulaglutinis var.Glutinisimmobilized ondiatomite were carried out. The Infraredspectroscopic study of cleancells surfaces and cells exposed tometal ions  was... see more

The results of  improving the standard parameters of the process of bacterial leaching of metals, which allow to shorten the term of carrying out technological process and increase the efficiency of the extraction of germanium and other useful compon... see more
