Adsorption of Basic Organic Colorants from an Aqua Binary Mixture by Diatomite

Observation of an anomalous adsorption in a critical binary mixture

2014 We have experimentally demonstrated the existence of a new critical anomaly in a binary mixture, due to the preferential adsorption of one of the components onto a solid wall. J.

Prediction of breathing and gate-opening transitions upon binary mixture adsorption in metal-organic frameworks.

Among the numerous applications of metal-organic frameworks (MOFs), a topical class of nanoporous materials, adsorptive separation is gaining considerable attention. Some of the most exciting candidates for gas separation processes exhibit structural transitions, such as breathing and gate opening. While predictive analytical methods are crucial in separation science and have been widely used f...

Ultrasonic Assisted Adsorption of Basic Dyes from Binary Component Systems onto ZnO Nanoparticles Loaded on Activated Carbon Derived from Almond Shell: Optimization by Central Composite Design

In this study, ZnO nanoparticles were loaded on activated carbon prepared from almond shell (ZnO-NP-AC). Then, this novel material applied as an efficient adsorbent for the ultrasonic assisted simultaneous removal of Basic Blue 41(BB41) and Basic Red 46 (BR46) in binary solution.  The efficiency of proposed activated carbon was enhanced by acid treatment and subsequent modification by physical ...

Adsorption of Acid blue 92 dye on modified diatomite by nickel oxide nanoparticles in aqueous solutions

Adsorbent prepared from waste plants for the treatment of dyeing effluents have high significance in environmental sustainability. In this research, adsorption of Acid Blue 92AB 92 dye from aqueous solutions on raw and modified diatomite nickel oxide nanoparticles was studied. The effect of different operation parameters such as pH, contact time, initial dye concentration, calcinations and sorb...

Removal of phosphate from eutrophic lakes through adsorption by in situ formation of magnesium hydroxide from diatomite.

Since in situ formation of Mg(OH)2 can efficiently sorb phosphate (PO4) from low concentrations in the environment, a novel dispersed magnesium oxide nanoflake-modified diatomite adsorbent (MOD) was developed for use in restoration of eutrophic lakes by removal of excess PO4. Various adsorption conditions, such as pH, temperature and contact time were investigated. Overall, sorption capacities ...
