HEAVY METAL-CONTAMINATED WATER PURIFICATION METHOD USING NANO-SIZED BIOGENIC MAGNETITE

摘要

Provided is a heavy metal-contaminated water purification method using nano-sized biogenic magnetite as a purifying agent. After metal-reducing microorganisms are cultured in an anaerobic medium containing akaganeite and glucose to form and collect nanoparticle magnetite, and the nanoparticle magnetite reacts with water contaminated by heavy metal such as hexavalent chromium (Cr6 +) to remove the heavy metal. Nano-sized magnetite particles can be manufactured by a simple process, and can be effectively applied to various industries by being environmentally friendly using microorganisms and synthesizing at a low cost.;COPYRIGHT KIPO 2017
