dc.description.abstractCottonseed cake as a low-cost and abundant by-product in Turkey was utilized as an adsorbent for the decolorization of Reactive Blue 19 (RB19) and Reactive Yellow 145 (RY145) from aqueous solution based on adsorption and ultrasound assisted adsorption. This study modeled effects of the following six factors on decolorization efficiency: the two process types, six initial pH values, three adsorbent concentrations, four temperatures, eleven reaction times, and five and eight initial dye concentrations of RY145 and RB19, respectively. The maximum decolorization efficiency was obtained consistently with ultrasound-assisted adsorption at the lowest initial dye concentration (300 mg/L of RB19 and 200 mg/L of RY145), the highest cottonseed cake concentration (1.5 g/L), and the highest temperature (55 degrees C). The best-fit multiple non-linear regression models were cross-validated accounting for 90.8% to 97.2% of variation in decolorization efficiency. Maximum adsorption capacities of cottonseed cake were estimated at 330.7 mg/g and 231.5 mg/g for RY145 and RB19, respectively. The adsorption kinetics of RB19 and RY145 on cottonseed cake was of endothermic and spontaneous nature.en_US
