Gallium removal is a research area focused on developing efficient methods for removing gallium from various materials or industrial processes. Gallium is a rare metal often used in semiconductor devices, LEDs, and solar panels, but its byproducts can be harmful to the environment if not properly managed. Researchers in this field explore techniques such as adsorption, precipitation, ion exchange, and membrane filtration to effectively separate and remove gallium from liquid or solid waste streams. The goal of these studies is to reduce the environmental impact of gallium-containing materials and ensure sustainable production and disposal practices.
