Title: Persistence and chemical distribution of arsanilic acid in three soils

Abstract

The persistence and chemical distribution of 4-aminobenzenearsonic acid (arsanilic acid), in Lakeland sandy loam, Hagerstown silty clay loam, and Christiana clay loam, were examined at two application rates (158 and 790 ppm) and at two moisture levels in soils established under aerobic and anaerobic conditions in the laboratory. Flooding was used to establish anaerobic soil conditions. Arsanilic acid was determined spectrophotometrically (520 nm) as the N-(1-naphthyl)ethylenediamine derivative, and arsenic (840 nm) was determined as an arseno-molybdenum blue complex. Total arsanilic acid, extracted sequentially by 1 N NH/sub 4/Cl, 0.5 N NH/sub 4/F, 0.1 N NaOH, and 0.5 N H/sub 2/SO/sub 4/ at 0, 2, 4, 8, 16, 24, and 32 weeks, disappeared rapidly from all three soils, whereas total arsenic remained constant in two soils and decreased some in Christiana clay loam. At the end of 32 weeks, less than 10% of the applied arsanilic acid could be extracted from any soil. It was concluded from extraction behavior that arsanilic acid formed salts with aluminum, iron, and calcium in the soil in the same manner as arsenate and phosphate. 17 references, 7 tables.
