ABSTRACT
Reuse of fluoride saturated bone char as a way of reducing fluoride in domestic water was investigated. The study was aimed at determining the most effective solution (NaOH, Na2CO3, NaHCO3 or Na3PO4) to use in the regeneration of fluoride saturated bone char. Effect of temperature on regeneration and removal capacity of regenerated bone char is also reported. Samples of 40 grams of bone char per 50 mL solution were used in determination of effectiveness of different sodium solutions. Samples were taken at contact times of 0.5-24 hours for fluoride analysis. Determination of temperature effect was carried out using 40 grams bone char/ 50 mL 1% NaOH solution, one-hour contact time and temperature of 20-60 . Removal capacity was determined using 40 grams bone char/ 50 mL natural water containing 5.96-ppm fluoride at contact time of 20 minutes. Fluoride and pH of unknown samples was analysed using fluoride and pH meter respectively. The data was analysed using Two Way Analysis of Variance to compare the efficiency of different concentrations of different solutions. NaOH solution was the most effective with 130.55-186.14 ppm and lowest was NaHCO3 with 4.35-6.03 ppm of fluoride released from fluoride saturated bone char. The efficiency of the four solutions was found to follow the order NaHCO3
