Nanocomposite to Detox Wastewater

Removing heavy metals through sorption High amounts of metallic elements, such as lead, cadmium and copper, make water toxic. Sequestration of these elements from water is the only possible way to make water safe for use. Recently, Rais Ahmad and Anam Mirza from the Aligarh Muslim University synthesised a chitosan-iron oxide nanocomposite to remove heavy… Read More ›

Removing Toxic Dye from Water

Using Ceiba Pentandra Seeds Toxic dyes released into water bodies by textile industries are a major environmental concern. One could use chemical precipitation, ion exchange, membrane filtration, coagulation, reverse osmosis, liquid–liquid extraction, ozonation, electrochemical oxidation, and electrodialysis to remove dyes from effluents. But they are expensive. Adsorption, on the other hand, is highly effective and… Read More ›
