In the present study we explored the adsorptive characteristics of 4-nitroaniline from synthetic aqueoussolution onto bagasse fly ash (BFA). Batch experiments were carried out to determine the influence ofparameters like initial pH (pH0), adsorbent dose (m), contact time (t) and initial concentration (C0) on theremoval of 4-nitroaniline. The maximum removal of 4-nitroaniline was determined to be 98% at lowerconcentrations (50 mg/L) and 41% at higher concentrations (300 mg/L), using a BFA dosage of 10 g/L at303K. Kinetic study of 4-nitroaniline removal by BFA was well represented by pseudo second-order kineticmodel. The 4-nitroaniline desorption from 4-nitroaniline loaded BFA shows that only 27% and 36% of4-nitroaniline could be recovered using ethyl alcohol and acetone respectively.
