Removal of Anionic and Cationic Dyes from Wastewater Using Activated Carbon from Palm Tree Fiber Waste

This study focuses on using a facile method for the green preparation of activated carbon (AC) from palm tree fiber (PTF) waste. The synthesized cost-effective AC was investigated removal an anionic dye (Congo red, CR) and cationic (Rhodamine B, RhB) wastewater. morphological structural characterization were performed by scanning electron microscopy (SEM), transmission (TEM), surface area, Fourier transform infrared spectroscopy (FTIR), total pore volume, average diameter size distribution, zeta potential, zero-point charge. To investigate adsorption efficiency, different parameters such as adsorbent dosage, solution pH, initial concentration, duration applied batch experiments. Various isotherm kinetics models to mechanism dynamics. results showed that chemical activation with weak acid (H3PO4) at 400 °C 30 min is fast each precursor produces high yield. result analysis increase in capacity pH 2. maximum 9.79 26.58 mg g−1 CR RhB dye, respectively. optimum dosage (PTFAC) 0.15 g percentage (98.24%) (99.86%) dyes. kinetic studies found be favorable feasible assessing dyes Langmuir model pseudo-second-order reaction, In addition, reusability up five cycles. environmentally friendly successfully removed
