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.
