Description

Sorption of rare earths from salt solutions on filled sorbent polyarsenazo-n is studied. It is shown that the sorbent can be applied for group concentration of rare earths from salt solutions. The group concentration conditions are the following: pH6 (≤0.5 M NaCl), volume rate of solution passage is 10 ml/min, solution volume is 0.5-2 l. The degree of extraction of lanthanum and europium from 0.5-2 l of solution is 95-100 %, concentration coefficients are (2.2-8.8)x102
