ABSTRACT: A study has been made of the use of fatty solvent extraction of mercury
from hydrochloric solutions. It was round that iso '
tractant for se gratin ,~ atr~y'1 alcohol is the best ex-
P ~, mercury from impurities in 2--~ M HC1. A method for
determining the chemic~:Ll spectrum was developed for Mg, Mn, Ag, !11 Pb, Ni, Cu,
