| Summary: | Spent grated coconut (cocos nucifera) modified with sulfuric acid (SSGC) from the
agricultural and food industry waste was developed as an efficient and new
biosorbent. In this study, the SSGC was chosen to be investigated for removal of
Ni(II) in aqueous solution. The column was set-up with fixed parameters; using 1 g
of biosorbent with flow rate of 10 mL/min. The experiment was carried out in the
initial Ni(II) concentration of 40 mg/L at pH of solution (4.5±0.5). The
breakthrough curve was obtained and the experimental data were modelled using
the Thomas and Yoon-Nelson models. Both models were fitted to this study with
coefficient correlation (R2) of 0.896. The adsorption capacity (qb) obtained from
breakthrough curve plot was 31.204 mg/g. |
