Abstract:The arsenic content in smelting by-product zinc carbonate is determined by Inductively Coupled Plasma Atomic Emission Spectrometry(ICP-AES) using acid-dissolved samples. Arsenic determination range is 0.02%~8.0%. ICP-AES method is established for the determination of arsenic in zinc carbonate, which is the by-product of smelting through some experiments including sample weighing, optimization of instrument conditions and interference of coexisting elements. After the standard addition recovery experiment, the standard addition recovery rate reaches 99%-101%, and the comparison experiment of this method and the spectrophotometry method is carried out, and the detection results are basically the same. The method is fast and accurate, and can meet the requirements for the determination of zinc carbonate sample.
