MCM-41 and Functionalized MCM-41 as Adsorbents to Remove Heavy Metals and Hardness from Contaminated Water and Groundwater

Leung S.W., Basnet N., Dejesus K., Lai J.C.K., Idaho State University, US

Mining operating and abandoned mines often have resulted in waste rock dumps and open pits that contain materials high in heavy metals and toxic elements. These contaminants are known to be present in groundwater, surface [...]

Analysis of Membrane Filtration Efficiency in Removal of Metal Oxide Nanoparticles from Aqueous Nanoparticle Suspension in the Presence of Coagulation Pretreatment

Surawanvijit S., Kim M., Cohen Y., University of California, Los Angeles, US

The introduction of nanoparticles (NPs) into aqueous environment is expected to rise with increased manufacturing and use of nanoparticles. There is a need to identify efficient and methods for NP removal and such methods must [...]

Removal of Zn(II) from Aqueous Solution by Biosorption using two Green Algal Species Oscillatoria sp. & Spirogyra sp.

Singh D., National Institute of Technology, Kurukshetra, IN

Pollution due to heavy metals has become an environmental problem of worldwide concern due to their increased discharge, toxicity, non-biodegradable and persistence nature. Major anthropogenic sources of heavy metals include metal extraction, metal fabrication, metal [...]

Fate, Transport, and Toxicity of Nanomaterials in Drinking Water

Zhang Y., Koeneman B.A., Chen Y., Westerhoff P., Capco D.G., Crittenden J., Arizona State University, US

The objective of this research is to evaluate the potential risk of human exposure to nanomaterials in drinking water by examining three issues: 1) characteristics and stability of nanomaterials in the water environment; 2) removal [...]
