| Abstract: | Benzotriazole in metal processing solution is determined by high performance liquid chromatography.A 125×4.6 mm Spherisorb cyano column is used in this method and 30% (vol.) methanol with 50 mmol/L KH 2PO 4 is used as the mobile phase.The determination wavelength is 260 nm.The recovery of the method is more than 97.8% and the detection limit is 0.1 μg/ml.The standard deviation is 0.2 for the 10 determinations of sample with 74.8 μg/ml benzotriazole. |
