Abstract. Textile wastewater has been a potential threat around the world. This study reports the abatement of rhodamine dye from textile wastewater using modified amberlite XAD-4 resin. Modification of resin was carried out by introducing amino group and characterized through FTIR. The peaks appeared at 1232 and 1624 cm-1 can be attributed to C-N stretching and N-H bending respectively, witnessed the presence of amino group on XAD-4. The effects of contact time, adsorbent dosage, initial dye concentration, and pH on dye removal were investigated. Maximum removal was recorded 93% at pH 9, adsorbent dosage 50 mg and 25 mgL-1 initial concentration dye solution and 60 min. The adsorption isotherm of dye showed good fitting to Langmuir and Freundlich isotherms models, respectively.The maximum adsorption capacities were calculated is 82.5 mg/g and 58 mg/g respectively.
