Abstract
The influence of the modified activated carbon activation type on the degree of adsorption of active chlorine from the aqueous solution was studied. The influence of water flow rate and purification process duration on the adsorption of active chlorine by modified activated carbon was researched and the optimal parameters of the dechlorination regime were determined. The proposed method of extraction of active chlorine by modified activated coal obtained from peach shells can be used in natural and sewage treatment processes for the removal of the active chlorine and chlorine compounds. The design of the mass transfer apparatus with a fixed layer of adsorbent has been developed. The technology of dechlorination aqueous solution by modified activated carbon allows to increase the efficiency of purification up to 99%.
