Textile dye effluent treatment was investigated using a novel biosorbent synthesized from Prosopis cineraria. The influence of operating variables, namely initial COD of the effluent (352-1,303 ㎎/L) and adsorbent dosage (0.25-4.0 g/L) on the removal efficiency was studied. The results of the biosorption experiments indicated that the equilibrium COD removal efficiency attained was 68% and COD uptake achieved was 90.52 ㎎/g at an optimal sorbent dose (2.0 g/L). Pseudo second order model fitted well to the experimental data and the rate constant was estimated as 0.098 x 10<SUP>-5</SUP> g /(㎎ min) .Chemisorption was identified as the removal mechanism involved. Power function model represented the kinetic data in selected range of COD and kinetic constants were estimated. XRF analysis of the biosorbent confirmed the presence of potassium oxide and calcium oxide as the two major components.
