【摘要】 研究了导数示波极谱法测定大气中微量的二硫化碳。在0.6900mol·L^-1乙醇-0.0970mol·L^-1二乙胺-0.0015mol·L^-1EDTA底液中,二硫化碳产生一灵敏的峰电流。峰电位为—0.64V（vs.SCE）。二硫化碳浓度在1.00×10^-2mol·L^-1～3.00×10^-5mol·L^-1范围内,浓度与峰电流具有线性关系。检测限为1.00×10^-5mol·L^-1。用本方法测定大气中的二硫化碳,取得了满意的结果。更多还原

【Abstract】 This paper studied on detemination of trace carbon disulfide in atmosphere by derivative oscillopolarography. A sensitive peak current of carbon disulfide can be obtained in the solution of 0. 69mol ?L-1alcohol-0. 097mol ?L-1diethylamine-0. 0015mol ?L-1 EDTA. The peak potential is about -0. 64V(vs. SCE). The concentration of carbon disulfide is linear with peak current in the of carbon disulfide is linear with peak current in the rang 1. 00×10-3mol ?L-1 to 3. OO×10-5mol ?L-1. The limit of detection for the determination of carbon disulfide is 1. 00×10-8 mol ?L-1. This method has been employed in the determina-tion of carbon disulfide in the atmosphere and be obtained successful results.更多还原
