Abstract

A comparative study was carried out on the adsorption of 4-nitroaniline (4-NA) on activated kaolinitic clay and Jatropha curcas activated carbon. The kaolinitic clay and Jatropha curcas were activated with 1 M HNO3 and 0.5 M NaOH respectively and were characterized using XRF, XRD, BET, SEM and FTIR techniques. The effects of various experimental parameters, such as initial 4-nitroaniline (4-NA) concentration, temperature, pH, contact time and adsorbent dosage on the adsorption process were investigated. The results obtained showed that Jatropha curcas activated carbon exhibited a better performance for the removal of 4-nitroaniline (4-NA) from aqueous media. The adsorption data were best fitted with Freundlich model. The experimental data of Jatropha curcas activated carbon fitted very well with the pseudo-second order kinetic model. This adsorption system was found to be independent of temperature.
