Extraction of Metal(Ti,V,Mo)-oxyl Cations by Monoacidic Phosphates and Phosphonates

摘要

The extraction of TiO2+,VO2+,VO2+ and MoO22+by HDEHP,HEHEHP and HDTMPP was studiedrespectively.The orders of extraction ability for the three extractant systems are as follows:for TiO2+,VO2+:HDEHPHEHEHPHDTMPP;for VO2+, MoO22+:HDEHP HEHEHP HDTMPP.The experimental results were discussed from the point of view of extractant structures.
