Abstract:
A method for J acid(2-amino-5-naphthol-7-sulfonic acid)in wastewater with high performance liquid chromatography(HPLC)is established. The J acid in wastewater treatment process is analyzed using the established method. HPLC is performed on a Krornasil-C18 column,using methanol and water(containing 4 g/L tetrabutyl ammonium)(35:65)as mobile phase and the detection wavelength of 230 nm. The results show that the calibration curve is linear in the range of 1.06～17.10 mg/L for concentration of J acid(r=0.999 6),precision is high,and its relative standard deviation is 1.92%. The method is rapid,accurate,and reproducible and can be used for quantitative analysis of J acid in wastewater and thus is provided as a good central control analysis method of treatment conditions of wastewater.
