Notable increases in metal consumption and declining ore grades in recent decades have
stressed the significance of dilute solutions as secondary sources of valuable metals …

The contamination of groundwater and surface water with nitrates is a global environmental
problem today. Elevated concentrations of nitrates lead to eutrophication of water bodies …

Cu (II) is a heavy metal found in water bodies and harmful to the environment and human
health. Thus, this study evaluated Cu (II) adsorption in rice husk using batch and fixed bed …

Modern methods of liquid waste disposal in the form of concentrates of various industries
were considered. It was shown that the most common thermal methods require significant …
