Most of the textile dye removal techniques operate within temperature and pH ranges of 20-60Â°C and 2-12, respectively. Both the pH and temperature have been reported to have significant effects on the efficiencies of the dye removal techniques. In this study, the effects of pH and temperature on the stability and color measurement (absorbance) of the textile dye remazol brilliant at different dye concentrations were investigated. Changing the pH from 1 to 13 and /or the temperature from 15 to 55Â°C did not have any significant effect on the absorbance of the dye remazol brilliant blue at two concentrations (65 and 300 mg L
