Adsorption behaviour of tri-n-butyl phosphate (TBP) from aqueous solution (dilute HNO<SUB>3</SUB>) on Amberlite XAD-4 has been investigated experimentally. Factors affecting the adsorption rates and breakthrough curves have been studied in batchwise and semicontinuous fixed bed adsorber. The adsorption isotherm of TBP on Amberlite XAD-4 resin have also been determined and the Freundlich model of adsorption is used to describe adsorption equilibrium. For the case of nonlinear equilibrium a simplified method proposed by Chi Tein is used to estimate intraparticle diffusion coefficient. The intraparticle diffusion coefficient is found to be in the range of 10<SUP>-8</SUP>cm<SUP>2</SUP>•s<SUP>-1</SUP>. Results of fixed bed column are used to estimate mass transfer zone (MTZ) length, length of unused bed (LUB), breakthrough capacity corresponding to fixed value of effluent concentration (5mg/l of TBP) and degree of saturation of bed at breakthrough. The MTZ lengthwas found to vary from 21.8cm to 37.3cm when flow rate changed from 13.5ml/min to 52ml/min, whereas column utilization ranged from 65.1% for the lowest flow rate to 43.5% for the highest flow rate.
