Abstract
Extraction of gold from electronic waste was commonly conducted using aqua regia. Here, we have shown a method to produce chloroauric acid in a salt solution by bipolar AC electrolysis. The developed bipolar AC electrolysis method provides an environment-friendly process to extract gold from electronic waste containing gold without using any strong acids such as aqua regia.
期刊介绍：
Gold Bulletin is the premier international peer reviewed journal on the latest science, technology and applications of gold. It includes papers on the latest research advances, state-of-the-art reviews, conference reports, book reviews and highlights of patents and scientific literature. Gold Bulletin does not publish manuscripts covering the snthesis of Gold nanoparticles in the presence of plant extracts or other nature-derived extracts. Gold Bulletin has been published over 40 years as a multidisciplinary journal read by chemists, physicists, engineers, metallurgists, materials scientists, biotechnologists, surface scientists, and nanotechnologists amongst others, both within industry and academia. Gold Bulletin is published in Association with the World Gold Council.
