Application of apophyllite and thomsonite natural zeolite as modified adsorbents for the removal of zinc from acid mine drainage.

Materials composed of natural zeolite have the potential to serve as highly effective adsorbents in the treatment of wastewater. The present study explores zeolite resin-based Apophyllite and Thomsonite as adsorbents for removing Zinc from acid mine drainage solution. The characteristics of the natural zeolites (Apophyllites and Thomsonite) are investigated using X-ray diffraction, Fourier-transform infrared spectroscopy and Field emission scanning electron microscopy analysis.

Acid treated RHWBAC electrode performance for Cr(VI) removal by capacitive deionization and CFD analysis study.

In this work acid-treated activated carbon was developed from rice husk, and it was used as raw material for Capacitive deionization (CDI) electrodes. The prepared acid treated rice husk waste biomass activated carbon (RHWBAC) electrode was used for the electrosorption of Cr(VI) from the aqueous medium. This RHWBAC electrode shows maximum electrosorption capacity was 2.

Tea waste biomass activated carbon electrode for simultaneous removal of Cr(VI) and fluoride by capacitive deionization.

Capacitive deionization is promising less energy based desalination technique to achieve pure water. In the present study microporous activated carbon was prepared from tea waste biomass by chemical and thermal modification. Further TWBAC was used for preparation of the electrode.
