Study on Extraction Separation of Heavy Metal Ions in Wastewater with Visible Spetrophotometry

Hongling Chen

Abstract

The distribution behavior of the two alternates of Pb(Ⅱ),Fe(Ⅲ),Cr(Ⅲ),Mn(Ⅱ) metal ion in sewage in the polyethylene glycol(PEG)-((NH4)2SO4)-pyrocatechol violet(PV) system was studied.The effect of the solution acidity,the amount of the extractant and the(NH4)2SO4concentration on the degree of extraction rate of metal ions was investigated.Through the control of certain conditions,extraction and separation of the Cr(Ⅲ),Pb(Ⅱ) and part of the mix between metal ions was realized.
