Abstract
The article presents data on the study of the sorption of heavy metal cations on the sediments of the Central depression of the Barents Sea. Experiments were carried out on sediments of natural humidity and after removal of silt water from them, on separate classes of size of sediments. The maximum values of the equilibrium exchange capacity of sediments containing and not containing silt water practically coincide with each other. Сapacity increases in the range (Mn < Ni < Zn < Cd) < (Pb < Cu) and ranges from 0,30 Mn to 0,71 Cu mg-eqv/g. According to the obtained values of the sediment capacity belong to the class of adsorbents. The influence of size, mineral composition of sediments and concentration of solutions of metal salts on the absorption capacity of sediments was studied. It is concluded that sediments can be considered as cleaners and pollutants of marine waters.
