METHODS FOR PREPARING TE(O) FROM TE(IV) USING METAL-REDUCING BACTERIA AND IRON ION

摘要

Disclosed is a method for preparing Te(O) in a low toxic form from toxic Te(IV) using metal-reducing bacteria and iron ions. According to the present invention, extracellular tellurium nanorods can be prepared through an environmentally friendly process and are able to provide tellurium utilizable in petroleum refining, electronic devices, batteries, and sensors.
