DOI: 10.1016/j.seppur.2019.03.100
Abstract: Abstract The selective recovery of copper(II) from Cu-Zn sulfate solutions using solvent extraction and N,N-dialkyl-N′-hydroxypyridine-2-carboximidamides as extractants was investigated. Three compounds were synthesized and their extractability toward copper(II) and zinc(II) was studied. The influence of… read more here.
