Summary: In this study, mixture activated carbon (MAC) was developed from a mixture of date palm wastes through hydrothermal carbonization and microwave-assisted H3PO4 activation. MAC showed mesoporous structure and negatively charged surface with various functional groups. The adsorption capacity of MAC for removing RBBR increased with initial concentration and achieved the maximum at pH 3 and 30 degrees C. Langmuir isotherm and pseudo-first-order kinetic models were the best fit for describing the RBBR-MAC adsorption system. The adsorption process was exothermic, increased randomness at the liquid-solid interface, and controlled by physisorption.
