Adsorption techniques offer unique advantages owing to the use of synthetic (eg, nanosized
metal oxides and polymer-functionalized nanocomposites) and natural (eg, clay and …

Heavy metals are discharged into water from various industries. They can be toxic or
carcinogenic in nature and can cause severe problems for humans and aquatic ecosystems …

Zeolites have been widely used for heavy metal removal due to their high cation exchange
capacity and surface sorption properties. However, the empirically determined adsorption …

Adsorption and ion exchange can be effectively employed for the treatment of metal-
contaminated wastewater streams. The use of low-cost materials as sorbents increases the …

Coal fly ash (CFA) is a solid waste generated by coal-fired power plants, and its massive
accumulation problem needs to be solved urgently. There are many ways of resource …

Among various methods adsorption can be efficiently employed for the treatment of heavy
metal ions contaminated wastewater. In this context the authors reviewed variety of …

The ever increasing consumption of coal around the world has given rise to the by-product
coal fly ash that requires an urgent attention and is gaining much needed research attention …

In the last few decades, fly ash, a coal combustion residue, has been used as a raw material
for synthesis of microporous aluminosiliceous minerals known as zeolites. Due to their …

An innovative adsorbent,“coal-analcime composite”, was converted from coal gangue
directly, that combined the adsorption effect of analcime and residual coal in coal gangue …

Low-cost zeolite sorbents, which have unique ion exchange and sorption properties, have
been investigated as candidates for cost-effective removal of heavy metals from waste …
