2.2.7. Effect of Temperature

Mixing the matching anion exchanger with the dye solution (C₀ = 250–18,000 mg/g) for 24 h at three different temperatures, 25, 35, and 45 °C, was used to investigate the effect of temperature on Direct Yellow RL sorption utilizing SBR and WBR. The samples were taken out, the solution was filtered out of the anion exchanger, and the concentration was evaluated using an absorbance value analysis.
