Scientists obtain pigments from spent zinc plating electrolytes

摘要

A Russian-Belorussian research team has come up with an innovative method for obtaining white pigments from toxic metallurgical waste.The method allows the production of high-quality industrial pigment while significantly reducing the toxicity of the raw materials.The study was published in the Journal of Chemical Technology and Biotechnology.[https://bit.ly/33wOEQI] Electroplating is a technique that adds a surface layer of metal to another type of metal through an electrolytic process.It is typically used to prevent corrosion and rust and improve the surface properties of metal objects.Zinc plating is the most common coating,with ammonium chloride-based solvent commonly used as the plating electrolytes.Despite their numerous advantages,current industrial processes involving electroplating remain amongst the most environmentally hazardous.Extremely toxic,cancerogenic heavy metal ions form in galvanic wastewaters due to the joint discharge of rinsing wastewater and spent electrolytes.
