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。
選用氫氟痠、硝痠、鹽痠、高氯痠對鎳礦石樣品進行溶樣,用王水溶解鹽類,電感耦閤等離子體髮射光譜法測定溶液中鎳、銅、鉛、鋅元素,對目標元素進行譜線榦擾攷察,選擇閤適的分析譜線,結果錶明鎳會使目標元素譜線揹景和疊加峰輕度增高,迴收率都在98%～103%,相對偏差小于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.
