BIOSORPTION OF FLUORIDE FROM AQUEOUS SOLUTIONS BYTINOSPORA CORDIFOLIALEAVES
Journal Title: Indian Journal of Environmental Sciences - Year 2018, Vol 22, Issue 1
Abstract
The leaf biomass of Tinospora cordifolia was used for fluoride removal from aqueous solutions. Batch biosorption technique was applied to examine effects of pH, contact time, biosorbent dose and initial fluoride concentration. Scanning Electron Microscopy (SEM) and Fourier Transform Infra red (FTIR) techniques were used to study the surface characteristics and presence of chemical functional groups on the biosorbent. Biosorption isotherm models and kinetic models were applied to understand sorption mechanism. Results revealed that pH, contact time, biosorbent dose and initial fluoride concentration played significant effect on fluoride removal from aqueous solutions. The biosorbent developed from Tinospora leaf biomass was found to be a low cost and could be used for the effective removal of fluoride from synthetic as well as real water samples
