Speciation Analysis of Arsenic in Copper Electrolyte Baths Using Liquid-liquid Extraction and ICP-OES Method Detection [PDF]
Archives of Metallurgy and Materials, 2022 The present study describes a method for the determination of As (III) and As (V) in copper electrolytes. The method is based on the separation of As (III) from a copper electrolyte by triple liquid-liquid extraction using a non-polar organic solvent in ...
