Biohybrid nanofibers containing manganese oxide–forming fungi for heavy metal removal from water

Heavy Metal Removal from Water and Wastewater Using Raw and Modified Diatomite (TECHNICAL NOTE)

heavy metal removal from water and wastewater was investigated by using raw and modified diatomite from Iranian mines. Modification of diatomite was done by impregnating the diatomite surface with 0.35 g of manganese oxide in one gram of diatomite. This modified diatomite was named Mn-Diatomite. The surface area measurements for Mn-diatomite showed a 2.2 fold increase, hence higher removal capa...

Heavy Metal Contaminants Removal from Wastewater Using the Potential Filamentous Fungi Biomass: A Review

The soil and water contaminations are frequently occurred by toxic heavy metals and organic pollutants as a consequence of human activities become a key concern in environmental and health problem. Several toxic metals (Cd, Cu, Hg, Pb, Mn, As, Ni, Zn, etc.) from industrial wastewater and other human activities are directly or indirectly released into the environment. Unlike organic contaminants...

Graphene-Based Microbots for Toxic Heavy Metal Removal and Recovery from Water

Heavy metal contamination in water is a serious risk to the public health and other life forms on earth. Current research in nanotechnology is developing new nanosystems and nanomaterials for the fast and efficient removal of pollutants and heavy metals from water. Here, we report graphene oxide-based microbots (GOx-microbots) as active self-propelled systems for the capture, transfer, and remo...

Applications of Magnetite Nanoparticles for Heavy Metal Removal from Wastewater

Heavy Metal Removal Using Dithiocarbamates

ajor emphasis is placed today on treating plating solutions and rinsewater to reduce the concentration of toxic metals to below established limits prior to discharge or water reuse. Available technology is adequate for partial treatment of most wastewater; however, new technology is needed to scavenge heavy metals from complexed or chelated compounds in rinsewater. Several report^^-'^ from this...
