Abstract

The interaction of the Sulfonic Acid Resin, Nalcite HCR, with CuII halide solutions was studied in hope of obtaining dissociation constants for the complex ions CuX+. The fact that CuX+ is absorbed by the resin to an appreciable extent prevented the attainmnet of this goal. It was found in the case of CuF+ that the complex ion is absorbed even more strongly than Cu++. The presence of a Cu++-F- complex was indicated by spectrophotometric observations.

The action of the carboxylic acid resin, IRC - 50 was studied in a column. It was found that the volume of the resin in the Cu++ salt form depended on the salt with which the resin was treated. In the case of solutions of Cu(OAc)2 it was found that Cu(OAc)+ was taken into the resin as well as Cu++.

A titration curve for IRC - 50 with NaOH in solutions of ionic strength one is given.
