Owing to the increasing use of magnesium alloys in the automotive, aerospace, electronics, and biomedical industry, more Mg-based wastes are being produced. Herein, a new process to electrochemically degrade Mg alloy wastes suitable for sewage treatment is described. Mg alloys are immersed in a sodium chloride solution and a small voltage is applied to accelerate degradation. The solid degradation products are composed of mainly nanostructured magnesium hydroxide and can be used to remove methyl orange from the simulated sewage effectively via adsorption/aggregation. This study provides insights into how to turn Mg wastes into useful forms to lessen the environmental impact.
