Removal of lead ions from aqueous solution by modified nanocellulose.

Heavy metals significantly impact the environment due to their non-biodegradable, toxic, and carcinogenic behaviors. Lead contaminants impose severe health impacts on humans and the water environment. Therefore, eco-friendly and efficient lead ion removal practices such as nanotechnology are an urgent requirement for the abatement of lead pollution.

Synthesis and characterization of zinc oxide nanocomposite for fluoride ion removal from aqueous solution.

In India, the problem of fluorosis has arisen in semi-urban and rural areas due to the intake of groundwater. The development and application of zinc oxide nanocomposite recently received a lot of attention for fluoride ion removal. Nanotechnology and nanocomposites are widely used by researchers to treat wastewater and control water pollution.
