Scope

Scope: This document specifies a method for determining aminobenzenesulfonic acid in soil using high-performance liquid chromatography. The detection limits for aminobenzenesulfonic acid, meta-aminobenzenesulfonic acid, and ortho-aminobenzenesulfonic acid are 0.1 mg/kg, 0.2 mg/kg, and 0.2 mg/kg, respectively. This document is applicable to the determination of aminobenzenesulfonic acid, meta-aminobenzenesulfonic acid, and ortho-aminobenzenesulfonic acid in soil. Main technical content: After extraction and purification, the aminobenzenesulfonic acid compounds in soil are separated and detected using high-performance liquid chromatography. They are qualitatively identified based on their retention times and quantitatively determined using an external standard method.
