电感耦合等离子体原子发射光谱(ICP-AES)法测定再生锌原料中铜、铅、铁、铟、镉、砷、钙、铝

采用硝酸、盐酸、氢氟酸(氟化氢铵)、高氯酸分解样品,电感耦合等离子体原子发射光谱法测定了再生锌原料中铜、铅、铁、铟、镉、砷、钙、铝的量。其测定范围:ω(Cu):0.01%～0.60%;ω(Pb):0.10%～5.00%;ω(Fe):0.10%～5.00%;ω(In):0.0100%～0.200%;ω(Cd):0.010%～3.00%;ω(As):0.10%～2.00%;ω(Ca):0.10%～10.00%;ω(Al):0.10%～4.00%。各元素的加标回收率为93%～113%。方法准确、快速、可靠,适用于再生锌原料中铜、铅、铁、铟、镉、砷、钙、铝量的同时测定。

Determination of Copper,Lead, Iron,Indium, Cadmium,Arsenic, Calcium and Aluminum Contents in Regenerated Zinc Materials by Inductively Coupled Plasma Emission Spectrometry

The sample was digested with nitric acid, hydrochloric acid, hydrofluoric acid (ammonium hydrogen fluoride) and perchloric acid. A method for the determination of copper, lead, iron, indium, cadmium, arsenic, calcium and aluminum in regenerated zinc raw materials was reported. The measurement ranges for Cu, Pb, Fe, In, Cd, As and Ca were 0.01% ~ 0.60%, 0.10% ~ 5.00%, 0.10% ~ 5.00%, 0.01% ~ 0.200%, 0.010% ~ 3%, 0.10% ~ 2%, 0.10% ~ 10% and 0.10% ~ 4%, respectively. The recoveries of the above-mentioned elements were 93%~113%. The method is accurate, rapid and reliable. It has been proved to be a convenient method for the determination of the contents of copper, lead, iron, indium, cadmium, arsenic, calcium and aluminum in regenerated zinc materials simultaneously.
