Adsorption Studies of Citrus maxima (Pomelo) Fruit Peels in the Removal of Lead (II) from Aqueous Solution
The ability of Citrus maxima or pomelo fruit peels for the removal of lead (II) ions in water was investigated. The influence of the different parameters such as pH, adsorption time, initial adsorbate concentration and adsorbent dosage in the adsorption characteristics was evaluated following the factorial design of experiment. Infrared spectral analyses of the adsorbent revealed the presence of hydroxyl and carboxyl bands in the structural backbone. Presence of plate-like and non-uniformity surface morphology can also be observed. Lead favors neutral to weakly basic conditions to achieve high percent removal. Lead adsorption studies in Citrus maxima followed the Temkin isotherm.
