Biosorption of Fluoride from Aqueous Solution Using Ulva fasciata sp.: A Marine Green Algae

Padmesh M.

Abstract


Water is a useful and vital natural resource for sustaining life and environment that we havealways thought to be available in abundance and free gift of nature. Enhanced industrialactivity during recent decades has led to the discharge of unprecedented volumes of industrialwaste water, which is a serious cause of environmental degradation. Excessive fluorideconcentrations have been reported in ground waters of more than 20 developed anddeveloping countries including India, where 19 states are facing acute fluorosis problems.This thesis presents results pertaining to the adsorptive studies carried out on fluorideremoval onto algal biosorbent (Ulva fasciata sp.). Batch sorption studies were performed andthe results revealed that biosorbent demonstrated ability to absorb the fluoride. Theparameters which influence the adsorption of fluoride, such as the fluoride concentration, thedosage of the adsorbent, the size of the adsorbent and the concentration of metal solutionstudies were investigated. Experimental data showed good fit with the Langmuir’s adsorptionmodel. Maximum fluoride sorption was observed at operating temperature.
