Activated carbon produced from palm fronds for elimination oxalic acid from polluted water sources

The purpose of this study is to develop low-cost palm frond activated carbon (AC) for the environmentally friendly elimination of oxalic acid from aqueous solution. The methods used activated carbon, which is generated by calcining AC at 600°C until it burns. The methods used activated carbon, which is generated by calcining AC at 600°C until it ignites. The samples were tested using FTIR, transmission electron microscopy, and nitrogen adsorption-desorption. Oxalic acid was adsorbed in a batch method with 0.5 g (AC) and 100 mL of solution at initial values ranging from 10 to 40 mg/L.
