Di- n -butyl Phosphorothioic Acid as an Extractant for Metal Ions.
Di-n-butyl phosphorothioic acid (5 w./v.% in CCl/sub 4/) was evaluated as a reagent for extracting metal ions from aqueous solutions of HCl or H/sub 2/ SO/sub 4/. The results are presented in two periodic table type charts as plots of log distribution ratio (D) vs. log STAH/sup +/!. Of 32 metal ions studied, 18 extracted in significant amounts. In general, metal ions that form insoluble sulfides have the highest D. The relative order of extraction of 11 metal di-n- butyl phosphorothioate complexes was determined. The effect of di-n-butyl phosphorothioic acid concentration on the D values for Ag/sup +/, Hg/sup 2+/, Zn/ sup 2+/ and In/sup 3+/ was investigated. The influence of various organic solvents on the D values for Hg/sup 2+/ and Zn/sup 2+/ was studied. The limits of extraction for Ag/sup +/, Hg/sup 2+/, and Pd/sup 2+/ were in the parts per billion range. The nature of the zinc di-n-butyl phosphorothioate complex was investigated. (auth)
