Abstract
Ferrous ion contamination in water is considered a complex and critical environmental problem due to rapid
Ferrous ion contamination in water is considered a complex and critical environmental problem due to rapid industrialization, human activity, and agricultural activities. Here, three adsorbent materials derived from palm leaves (PL), known as PL, modified PL (mPL) and biochar-derived PL (BPL) were prepared and utilized to eliminate Fe (II) from aqueous solution. The effects of pH, shaking time, amount adsorbent, and initial Fe (II) concentration were performed in a batch adsorption technique. The maximum removal of Fe (II) at initial concentration of 5 ppm, pH 5, contact time 80 min, and 0.05 g were 77. 96, and 86% for the PL, mPL and BPL, respectively. The kinetic study showed that the adsorption of Fe (II) ions onto our adsorbents obeyed the pseudo-second-order kinetic model. Furthermore, the adsorption isotherms confirm that the adsorption of Fe (II) ions onto the PL, mPL and BPL obeyed the Langmuir model, verifying the chemical adsorption mechanism. Palm leaves proved high adsorption efficiency toward Fe (II) ions in the aqueous media.
