Abstract Synthetic dyes in wastewater present a challenging problem that requires special attention due to the high environmental risks, and magnetic adsorbents appear as promising alternatives solve it. Magnetic activated carbons (MAC) were prepared by comparing single- multi-step methods. Palm kernel shells used precursors, with ZnCl 2 , then magnetized adding solution containing Fe 3+ ions (FeCl 3 ). Iron compound inclusion aims enhance effectiveness of carbon an adsorbent for liquid waste. Fourier transform infra-red characterization showed functional groups detected on MAC O–H, C═O, C═C, C≡N, C–O. The effect preparation methods dye concentration (10–30 mg·L −1 ) adsorption kinetics investigated. Characterization through pyrolysis (M-MAC) has larger pores, achieving capacity up 6.953 mg·g 28% removal efficiency, making it superior performance. Furthermore, data fitted well Redlich–Peterson isotherm model R = 0.9788 M-MAC, while agreed both pseudo-first-order pseudo-second-order models. Moreover, NaOH successfully recovered desorption efficiencies 98.34%.
