Scope
Scope: This standard specifies the detection method for 4-aminoazobenzene derived from certain azo dyes in textile products using high-performance liquid chromatography (HPLC/DAD). This standard is applicable to various textile products processed by dyeing and printing. Main technical content: The samples are reduced with sodium dithionite in an alkaline medium, extracted using a suitable potassium carbonate-acetonitrile two-phase system, and the extracted 4-aminoazobenzene is quantified using high-performance liquid chromatography with a diode array detector (HPLC/DAD) through the phase critical point distribution method of the cloud point method.
