Preparation and Characterization of Bagasse Ion Adsorbent
A low-cost adsorbent was prepared simply by phosphorylating bagasse. The materials were characterized by Fourier Transform Infrared (FT-IR). Batch adsorption studies were carried out for Cu (II) ions adsorption at different initial concentrations. The pseudo-first-order, pseudo-second-order and the intra-particle diffusion models were used to analyze the kinetic data. The results revealed that the pseudo-second-order model generated the best agreement with the experiment data with the correlation coefficients greater than 0.999 for the adsorption systems. The mechanism of the Cu (II) ions adsorption by the phosphorylated bagasse was also discussed. The FT-IR results showed that the bagasse adsorbent has many different functional groups and these functional groups are able to react with Cu (II) ions in aqueous solution.
