Bentonite - an overview ScienceDirect Topics

Bentonite has little anion-exchange capacity. Thus, it is relatively ineffective in removing either neutral or negatively charged proteins. Thankfully, the latter have few, if any, significant sensory influences. Through ion exchange, cations such as copper, potassium and zinc also tend to be removed.

Behavior of bentonite in an aqueous electrolytic

In this study, we used aqueous solutions containing 1 mg/L of Cd 2+ for electrolysis while varying the current density (CD), amount of bentonite added and the effective submerged area to investigate the adsorption capacity of Cd 2+ ions onto bentonite by electrolytic aggregation. The adsorption of Cd 2+ ions increased with increasing amount of bentonite added to the electrolytic solution.

Synergistic modification of bentonite by acid

2020-4-1  Bentonite has been considered to be a promising adsorbent because of its lamellar structure, high cation exchange capacity, and low price with resource abundance (Pereira et al. 2017). Many researchers have tried to modify bentonite to enhance the adsorption capacity for cationic dyes (Selvam et al. 2008; Farhan et al. 2014).
