Abstract
A spectrophotometric method is presented for the determination of arsenite, arsenate, and phosphate in fresh and salt waters. By the use of an oxidizing and a reducing reagent, these species may be determined in a mixture of all three. Appro priate conditions for the use of these reagents are described. The method is applicable to solutions where the total phosphorus and arsenic molar concentration is less than about 3 · 10−6. The precision is of the order of ±0.015 μM. © 1972, Elsevier Publishing Company. All rights reserved.
