Abstract: In this study, activated carbon derived from Alocasia indica (Taro) was used for the removal of Fe(II). pH of 6, dosage of 3g/L with time of contact 80 mins were the optimal conditions obtained in the batch experimentation process. The adsorbent surface area was identified by BET technique and characterized by Scanning electron microscopy (SEM) and Energy dispersive X-ray measurements (EDAX). The adsorption kinetics study reveals that the kinetic data follows Pseudo-2nd -order with higher R2 of 0.99 and lesser chi square value of 0.001. From the experimental data, it was observed that isotherm model fitted well with Langmuir isotherm with maximum adsorption capacity of 4.975 mg/g and R2 value of 0.98, indicating chemical adsorption and formation of homogenous surface. Thermodynamic studies revealed that the adsorption process is spontaneous and endothermic.
