Removal of Bisphenol-A from Aqueous Solution Using Rice Husk Nanosilica: Adsorption Kinetics, Equilibrium and Thermodynamic Studies

This study evaluates the adsorption of bisphenol-A (BPA) from aqueous solutions using nanosilicaobtained from rice husk. Nanosilica (79 nm) was extracted from acid and thermal treated rice huskwaste. The rice husk nanosilica (RHS) was fully characterized through X-Ray DiffractionSpectroscopy (XRD), Scanning Electron Microscopy (SEM), X-Ray Fluorescence Spectroscopy(XRF) and Fourier Transmittanc...

Removal of tetracycline from wastewater using pumice stone: equilibrium, kinetic and thermodynamic studies

In this study, pumice stone was used for the removal of tetracyline (TC) from aqueous solutions. It was characterized by XRD, FT-IR, SEM and BET analyses. Cation exchange capacity of pumice stone was found to be 9.9 meq/100 g. Effect of various parameters such as solution pH (2-11), adsorbent dosage (0.5-10 g/L), contact time (2.5-120 min), initial TC concentration (5-300 mg/L) and temperature ...
