| 摘 要： | 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。 |

| Abstract: | In alkaline media,malachite green could enhance the chemiluminescence(CL) of potassium ferricyanide and calcein greatly.The relative CL intensity was linear with malachite green concentration over certain scope.Based on the observation,a new method for the determination of malachite green has been established by chemilumines cence combined with flow injection technique.Under the optimum conditions,the linear response range of this method was 3.0×10-8-1.0×10-6g/mL and the detection limit was 2.5×10-9g/mL.The relative standard deviation(RSD) was 2.3% for the 11 replicated determinations of 1.0×10-7g/mL malachite green. |
