摘要
A method for determination of arsenic(V) in the range between 1 × 10-7 and 1.2 × 10-6M has been developed. These levels are reached by means of the multiplication factor yielded by use of 12-molybdoarsenic acid and the great sensitivity of polarographic determination of the Mo(VI) in the heteropoly acid. The procedure has been successfully applied to determination of arsenic in copper alloys, after selective extraction of phosphorus. © 1990.
