A solid-phase extraction method, based on the adsorption onto Diaion HP-20 resin, was developed forsimultaneous spectrophotometric determination of Lanaset Blue 2R and Lanaset Yellow 28 dyes whichare most together hazardous textile dyes in wastewater. Concentrations of the dyes were determinedusing UV–visible spectrophotometer at 625 and 438 nm for LB-2R and LY-28, respectively. Thedeveloped method was also applied to water samples. In dying process water, 572 15 mg/mL and396 6 mg/mL of LB-2R and LY-28 dyes were determined. In addition, adsorption isotherms of the method,point of zero charge and surface micrographs of the resin were investigated.
