摘要: In this article, a carbon cloth composite electrode modified with gold nanoparticles (AuNPs) was prepared by facile in situ electrodeposition method and applied to the detection of mercury ions water. With optimized electrochemical conditions methods, limit (LOD) 0.6 μg L-1 linearity ranging from 2 200 SWSV method, showed good repeatability after many cycles. Based on continuous flow system constructed Hg environmental water samples. The standard addition experimental results two real samples an level 10 50 that recoveries were between 92.4% 108.9% RSDs 2.01% 3.22%. These same performance as ZAAS (recovery: 94-102.4%, RSD 2.09-5.4%). Compared other materials, shorter time, wider linear range high stability similar LOD can be achieved using electrode. established would have promising application online real-time heavy metals
