| 摘 要： | 采用过氧化钠分解试样,盐酸浸取,通过仪器参数的优化、共存元素干扰等实验,建立了电感耦合等离子体原子发射光谱法测定电镀废弃物中镍含量的方法。方法的测定范围ω(Ni)1.00%~10.00%。经加标回收实验,镍元素的加标回收率为99.0%~107%(n=3),方法准确可靠,完全能够满足此类物料中镍含量的检验工作。

| Abstract: | In this paper,an inductively coupled plasma atomic emission spectrometry(ICP-AES)method for determination of nickel content in electroplating waste has been established by using sodium peroxide alkali fusion,through sample melting time and temperature,instrument conditions,interference experiments of coexisting elements,etc.Determination range:ω(Ni):1.00%-10.00%.The recovery rate of nickel is 99%-107%(n=3)through the standard addition recovery experiment.The method is accurate and simple,and suitable for nickel determination of electroplating waste. |
