ARSENIC REMOVAL FROM WATER USING ACTIVATED CARBON DERIVED FROM PELTOPHORUM PTEROCARPUM (COPPER POD)

Abstract

The removal of Arsenic from synthetic sample by adsorption on chemical activated carbon prepared from Peltophorum Pterocarpum (Copper pod) fruit have been carried out at room temperature 32 ± 1 o C. Batch tests were conducted for the removal of Arsenic on chemically activated (Calcium chloride) carbon with Impregnation ratio's (I.R) 0.25, 0.50 and 0.75 for optimum time, optimum dosage and optimum pH. The maximum removal efficiency was obtained at an I.R. ratio of 0.75 and hence an I.R. of 0.75 has been taken for all the batch and column adsorption tests conducted. The optimum contact time, adsorbent dose and pH for carbon with I.R-0.75 was 10min, 75mg and 8.75, respectively, with arsenic removal efficiency of 97.32%, 99.33% and 99.33% respectively has been observed. Further, results of adsorption column studies data showed best fit with Freundlich Isotherm.
