| Abstract: | 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. |
