Summary

Estimation of Cr(VI) in Water, Tannery and Plating Wastes

A zirconium tellurite membrane exhibits good selectivity for CrO4 2− or CrO7 2− ions at pH 3–6 and 8–11. Membrane electrode can be used to determine the activity of Cr(VI) ions in the concentration range 10−1 to 7×10−5 M at specified pH. The response time is 30 s and a large number of anions and cations do not interfere with the functioning of this assembly. It has been tried for the estimation of Cr(VI) in plating and tannery waste.
