Abstract: The content of sulfuric acid and zinc ion in zinc electrolyte directly affects the purity and product quality of zinc. At present, the detection of sulfuric acid and zinc ion content in electrolyte depends on offline detection, the degree of automation is low, and the research and application of combined determination device is less. In this paper, the photometric titration on-line analysis system is introduced, and the content of sulfuric acid and zinc ion is determined by optimizing the detect... More
