Abstract

A plant-based demulsifying agent for electrocoppering sewage at least contains radix isatidis extracts, Poria cocos extracts, fructus quisqualis extracts, flos chrysanthemi extracts, shiitake extracts, folium perillae extracts and water.

Description

technical field [0001] The invention relates to electroplating copper sewage treatment, in particular to a plant-based demulsifier for electroplating copper sewage. Background technique [0002] Nonylphenol polyoxyethylene ether is a nonionic surfactant with good penetration, emulsification, dispersion, anti-acid, anti-alkali, anti-hard water, anti-reduction, and anti-oxidation capabilities. It is widely used as W / O emulsifier or O / W emulsifier and dispersant, and is the main raw material of synthetic detergent. Nonylphenol polyoxyethylene ether can be used as a brightening agent for acidic bright copper plating carrier. It can hinder the Cu adsorption layer on the surface of the electrode 2+ Diffusion has the effect of enhancing polarization and refining grains. However, once nonylphenol ethoxylates enter the environment, they will quickly decompose into the more toxic environmental hormone nonylphenol. Nonylphenol is recognized as an environmental hormone worldwide. S...
