Experimental research was conducted in order to point out the issue of dye removal from textile wastewater. Dyes are among the most dangerous substances emitted into the environment from the textile industry. The aim of this study was to determine the adsorption efficiency of the removal of naphthol green B from artificially contaminated water using Purolite MB400 ion exchange resin. In experimental research was used 0.3-1.2 mm fraction of Purolite MB400. 6 samples were prepared for this analysis. The experiment of sorption was performed at the same pH level, which ranged from 6 to 7. In order to find out whether the changes of the pH values of the solution after the sorption process did not affect the sorption process itself, optical density measurements were performed at different pH values. pH values ranged from 6 to 8.5. The sorption process was performed for 1 hour. A calibration curve at 484 nm was generated before measurements using Photo colorimeter. The residual carbon content of the samples was determined using a carbon analyzer. After 60 min of the adsorption process, the adsorption efficiency of the dye ranged from 50.96 % to 98.30 %.
