Scope
Scope: This document specifies the flow injection 4-aminobenzylidine spectrophotometric method for determining the content of volatile phenols in soil. This document is applicable to the determination of volatile phenols in soil. When the sampling amount is 20 g and the detection optical path is 10 mm, the detection limit of volatile phenols (calculated as phenol) determined by this method is 0.02 mg/kg, and the determination lower limit is 0.08 mg/kg; Main technical content: This standard is applicable to the determination of volatile phenols in soil. The main technical content includes the scope of application, normative reference documents, terms and definitions, method principle, interference and elimination, reagents and materials, instruments and equipment, samples, analysis steps, result calculation and expression, precision and accuracy, quality assurance and quality control, and precautions, etc.
