In this study, activated carbon (ACs) adsorbent was synthesized using the two steps of hydrothermal carbonization (HTC) followed by activation. The hydrothermally produced char of BSP was activated to produce porous activated carbon BSPAC, where K2CO3was used asa chemical activating agent. Box Behnken Design was used to optimize the input variables of pyrolysis temperature (Al), residence time (B,), and ratio (Cl) for the pyrolysis process. Removal percentage 034 percentage carbon yield 032), and fixed carbon 033) percentage were chosen as output responses. The analysis of variance was utilized to generate appropriate mathematical models with subsequent statistical analysis. Physiochemical characterizations were carried out for the hydrothermally carbonized sample (BSPC) and the optimized activated sample (BSPAC). Langmuir, Freundlich, and Temkin models were employed to estimate the isotherm model parameters. The results demonstrated that HTC with subsequent mild activation using K2CO3 can be considered as a greener route to obtain better-quality porous carbon having surface area of 599 m2/gm for removal of Cu(II) cations from wastewater.
