中文摘要: 采用王水消解-电感耦合等离子体原子发射光谱(ICP-AES)对辛菌胺生产工艺中产生的危险废物工业盐中9种重金属元素Cu、Zn、Cd、Pb、Cr、Be、Ba、As、Ni 同时进行测定。研究了固液比、提取时间、提取温度等对样品重金属浸出浓度的影响,并通过高盐基体同重金属元素一起建立标准曲线以消除基体干扰。9种重金属在各自的检测范围内线性关系良好,相关系数均大于0.999,方法的检出限为0.0001~0.03 mg/L,测定结果的相对标准偏差为 0.20%~1.84%,样品加标回收率为 93.0%~104.6%,废盐中杂质元素含量均未超过GB 5085.3-2007中浸出毒性危害成分浓度限值。该方法操作简便,测定快速、结果准确并且检出限低,满足测定要求,适用于高盐危险废物中9种重金属元素的浸出毒性分析测定。
Abstract:Aqua regia digestion-inductively coupled plasma atomic emission spectrometry (ICP-AES) was used to simultaneously determine 9 heavy metal elements Cu, Zn, Cd, Pb, Cr, Be, Ba, As and Ni in the industrial salt of hazardous waste produced in the production process of xinjun’an. The effects of solid-liquid ratio, extraction time and extraction temperature on the leaching concentration of heavy metals were studied, and the standard curves were established by high salt matrix together with heavy metal elements to eliminate matrix interference. The 9 heavy elements had good linearity in the detection ranges with correlation coefficients more than 0.999, and the detection limits of the method were 0.0001~0.03 mg/L. The relative standard deviations RSDs of the results were 0.20%~1.84% , and the recoveries of standard addition were 93.0%~104.6%. The method has the advantages of simple operation, rapid determination, accurate results and low detection limit which meet the measurement requirements. It is applicable to the leaching toxicity analysis of 9 heavy metal elements in high salt hazardous wastes.
