Selective adsorption of heavy and light metals by natural zeolites
Recent studies have shown that zeolite can be applied through an ion-exchange process to remove metals from solutions. In this paper the potential of two zeolites to perform as sorbents for treatment of multi-metal system ...
Metal ions adsorption affinity of clayey materials from the North West Province of South Africa
Local clays that are abundant in the periphery of Potchefstroom in South Africa were characterized and investigated as potential sorbents for the removal of metal ions from effluents. The clay samples mostly contained ...
Bentonitc clay adsorption affinity for anionic and cationic dyes
The incidence of dye pollution in South Africa is quite alarming, requesting effective and affordable techniques to curb further degradation of the limited water resource. Adsorption is an attractive technique due to a ...
