基于在碱性条件下,孔雀石绿可以增强铁氰化钾-钙黄绿素的化学发光,且其浓度在一定范围内与化学发光强度呈线性关系,结合流动注射技术,建立了化学发光法测定孔雀石绿的新方法。在优化的实验条件下,方法的线性范围为3.0×10-8～1.0×10-6 g/mL,检出限为2.5×10-9 g/mL,对浓度为1.0×10-7g/mL的孔雀石绿溶液进行11次平行测定,相对标准偏差为2.3%。方法可应用于环境水样的测定。
Based on the alkaline conditions, malachite green can enhance the chemiluminescence of potassium ferricyanide-calcein, and its concentration within a certain range and chemiluminescence intensity was linear relationship, combined with flow injection technology, the establishment of a chemiluminescence method for the determination of peacocks Stone green new method. Under the optimized experimental conditions, the linear range of the method was 3.0 × 10-8 ~ 1.0 × 10-6 g / mL with the detection limit of 2.5 × 10-9 g / mL and the concentration of 1.0 × 10-7g / mL Of malachite green solution 11 parallel determination, the relative standard deviation of 2.3%. The method can be applied to the determination of environmental water samples.
