摘要
采用硝酸+酒石酸溶解试样,电感耦合等离子体原子发射光谱(ICP-AES)法测定高铋铅中的铜、铁、镍、镉、砷、锑和铋的含量。测定范围为ωCu(0.10%~5.00%)、ωFe(0.001%~0.10%)、ωNi(0.001%~0.10%)、ωCd(0.001%~0.050%)、ωAs(0.50%~7.00%)、ωSb(0.50%~5.00%)、ωBi(1.00%~7.00%)。经加标回收实验,各元素的加标回收率为91.5%~115%。方法准确简单,适用于高铋铅中铜、铁、镍、镉、砷、锑和铋量的同时测定。
Using nitric acid and tartaric acid to dissolve the sample,the contents of copper,iron,nickel,cadmium,arsenic,antimony and bismuth in high bismuth lead were determined by inductively coupled plasma atomic emission spectrometry.Determination rangeωCu(0.10%—5.00%),ωFe(0.001%—0.10%),ωNi(0.001%—0.10%),ωCd(0.001%—0.050%),ωAs(0.50%—7.00%),ωSb(0.50%—5.00%),ωBi(1.00%—7.00%).The recovery of each element is 91.5%—115%.The method is accurate and simple.It is suitable for the simultaneous determination of copper,iron,nickel,cadmium,arsenic,antimony and bismuth in high bismuth lead.
