This paper presents the results of a comparative assessment effectiveness sorption purification aquatic medium and fertile soils using native forms bentonite clays deposits in Belgorod region (Russia) from heavy metal ions (Cu 2+ , Fe 3+ Cr Pb ) radionuclides ( 137 Cs, 85 Sr, 233 U и 239 Pu). It was revealed that during model water systems, most absorbing activity is shown by natural Polyana Ne...

The processes of self-purification nature due to the high concentration xenobiotics and resistance decomposition are very slow. Therefore, an urgent environmental task is restore environment: rational processing industrial agricultural waste, restoration land fertility from toxic chemicals, disposal sludge sewage treatment plants, purification water sources, etc. Among above problems production...

Phytoremediation is an emerging concept for contaminated soil restoration via the use of resilient plants that can absorb contaminants. The harvested biomass be thermochemically converted to energy carriers/chemicals, linking decontamination with biomass-to-energy and aligning circular economy principles. Two thermochemical conversion steps biomass, both used treatment/exploitation, are conside...

The rate constants of the Diels-Alder reaction 9,10-dimethylanthracene with tetracyanoethylene, 4-phenyl-1,2,4-triazoline-3,5-dione, maleic anhydride, and N-phenylmaleimide in solution have been determined. It was found that tetracyanoethylene 4-phenyl-1,2,4-triazoline-3,5-dione can react instantly 9,10-dimethylanthracene, which is a representative toxic polycyclic aromatic hydrocarbons. kineti...
