| الملخص: | The removal of phosphate ion from aqueous solution by natural sponge gourd fibre was investigated at different contact time and initial phosphate concentration according to batch method. As comparison, a similar study was carried out using pretreated sponge gourd fibre. The final phosphate concentration was determined according to Ascorbic Acid method. The results showed that the adsorption process
for both natural and treated sponge gourd fibre was rapid during the first 10 minutes. Equilibrium, however, was attained after 60 minutes. The adsorption fitted well to
pseudo second order kinetic model. Phosphate adsorption by natural sponge gourd fibre fitted well to Freundlich isotherm while the pre-treated sponge gourd fitted well
to Langmuir isotherm. The maximum adsorption capacity of natural and treated sponge gourd fibre was 87.7 µ/g and 2500 µ/g, respectively. Overall, pre-treatment of the sponge gourd fiber increased its phosphate adsorption efficiency. |
