Synthesis of Copper Sulfide Nanoparticles and Its Application to the Determination of Mercury Ion
Abstract:
With citrate as a stabilizing agent,CuS nanoparticles were synthesized in aqueous phase. This article is to study the effects of resonance light scattering between CuS nanoparticles and mercury ions under the conditions of different pH values and the ratios of sodium sulfide and copper sulfate.Under optimum conditions,the method to determine trace mercury in water was established. The results showed that in the optimum experimental conditions,the intensity of resonance light scattering has a good linearity(r=0.991) in the range of 0.01~100 μmol/L with a detection limit of 0.003 μmol/L.The recovery is in the range of 100.3%~103.4% for Hg2+ detection in environmental water sample.
