Sorption of Heavy-Metal Ions And Radioactive Cesium By 'Ultrasorb' Composite Sorbent

摘要

Data are given on the sorption of the heavy-metal ions (Fe~(3+), Co~(2+), Cd~(2+), Pd~(2+), Zn~(2+), Cu~(2+) and Ni~(2+)) and radioactive isotope ~137Cs from Ringer salt solution by Ultrasorb composite sorbent, which has two components: the modified clay mineral palygorskite (palygorskite-M) and a modified fibrous carbon sorbent of AUT-M type (UVM-Ts). Selectivity series have been determined for the sorption of these toxic metals on the basis of the calculated distribution coefficients K_d under standard conditions. It is shown that the properties of the components combine well in the material, and it is proposed for use as a treatment agent (enterosorbent) having a selective action in the treatment of diseases due to the accumulation of heavy metals and radionuclides in the body.
