Adsorption of Nickel (II), Copper (II) and Iron (III) on Kammoni Leaf Powder: A Case Study

The study was performed to investigate the use of Kammoni plant material (L. Solanum nigrum) as an adsorbent for the removal of Ni (II), Cu (II) and Fe (III) from aqueous solution. FT-IR characterization of Kammoni Leaf Powder (KLP) done by standard procedures. The adsorption process was carried by batch experiments by varying adsorbent dose, pH of the adsorbate (metal ion) solution, temperature and time. The percentage removal of Ni (II), Cu (II) and Fe (III) by KLP under different condition during the findings was significant. The order of adsorption during the findings on KLP of metal ions were Ni > Cu >Fe. The equilibrium adsorption data were fitted with Freundlich, Langmuir Isotherms. A time variation study indicates that adsorption follows pseudo-first order kinetics.
