Extraction chromatographic studies of mercury(II) and some other metal ions on Chromosorb 102 loaded with triisobutylphosphine sulfide. Its application to industrial effluent

Batch experiments on the uptake of Hg(II) from nitric acid medium by Chromo sorb 102 impregnated with Cyanex 471X have been conducted. The effect of di fferent variables like equilibration time, concentration of acid, metal ion and extractant has been studied. Binary separations of Hg(II) from Cr(III) , Fe(III), Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Pb(II) on rev ersed phase columns have been achieved. Experiments have been conducted to evaluate the recycling capacity of the reversed phase columns. The practica l utility of the proposed columns has been demonstrated by decontaminating mercury containing waste effluent from a paper and pulp industry.
