Investigating the efficiency of tamarind seed powder in defluoridation of water :

Abstract

This paper begins with an overview of the origin, magnitude geographical distribution and health consequences of fluoride contamination problem around the world arid particularly in Osukuru. Sub County.

Tamarind seed a household waste from the kitchen is. used for the sorptive removal of fluoride from synthetic aqueous solution as well as from' field water samples. The main aim of this study was to investigate the efficiency of tamarind seed 'powder for defluoridation of ground water. Various current defluoridation technologies are discussed and this paper mainly focused on adsorption.

Batch sorptive defluoridation was conducted under variable experimental conditions such as agitation time, initial fluoride concentration, and sorbent dose. Maximum defluoridation was achieved in within 80minutes. defluoridation capacity increased with increase in sorbent dose and equilibrium was reached when increase in sorbent dose.gives no appreciable change. in the amount of fluoride removed, moreover defluoridation decreases with increase in initial fluoride concentration. The optimum efficiency for both synthetic and-field water samples were found to be. 96% and 90% respectively. For domestic application, defluoridation with 1 00% achievement was reached.
