Adsorption of Cadmium Ions from Aqueous Solutions on Modified Sorbents

Some new modified sorbents based on opoka from Astrakhan region were obtained. A comparative study of the sorption of cadmium ions on the surfaces of the sorbents was made. Also the static adsorption isotherm of substances from aqueous solutions was studied. The change of enthalpy, isobaric-isothermal potential and entropy of sorption and kinetics of cadmium ions sorption from water solutions were calculated. The results of the study can be used for the water purification from cadmium ions

SORPTION PURIFICATION OF NATURAL WATER FROM MICRO-MIXTURES OF HARD METALS

The research determines the efficiency of the use of activated carbon in the process of water purification from heavy-metal ions for technological purposes in the food industry. Comparative studies of the use of sorbents of various types of activated carbon have been carried out. The study determines the factors that influence the efficiency of drinking water purification from heavy metal ions through activated carbon. It also proves the highest efficiency of oxidized form of activated carbon
