电感耦合等离子体发射光谱法测定镍矿石中镍铜铅锌

Determination of Ni,Cu,Pb and Zn in nickel ores by inductive coupling plasma-atomic emission spectrometry

选用氢氟酸、硝酸、盐酸、高氯酸对镍矿石样品进行溶样,用王水溶解盐类,电感耦合等离子体发射光谱法测定溶液中镍、铜、铅、锌元素,对目标元素进行谱线干扰考察,选择合适的分析谱线,结果表明镍会使目标元素谱线背景和叠加峰轻度增高,回收率都在98%～103%,相对偏差小于3。

The authors dissolved the sample of the nickle ore with hydrofluoric acid,nitric acid,hydrochloric acid and high chloride acid.Dissolved the salt with aqua regia.To determine the elements of nickel,copper,lead and zinc in the solution by inductive coupling plasma-atomic emission spectrometry,to interfere survey the target elements in spectrum lines,and to select the suitable analytical spectral lines.The result of the experiment proves that the nickel can increase the spectrum line background and overlapping peak of the target elements,In addition,the recovery rate ranges from 98% to 103%,and the relative deviation less than 3.
