Entrapment of green seaweed Caulerpa Scalpelliformis for extracting Pb(II), Ni(II) and Zn(II) metal ions from aqueous solutions
Abstract:<p>From this study, green seaweed Caulerpa Scalpelliformis is utilized as a sorbent for the removal of three metals such as lead (Pb), nickel (Ni) and zinc (Zn). Adsorption tests showed that maximum removal efficiency of 75.02% for Pb, 80% for Ni and 91.11% for Zn was obtained at an optimal equilibrium pH of 7 for Pb and 6 for Ni, Zn, 2g/L sorbent at an ionic strength of 100 mg/L of 30°C. Four isotherm models, such as Langmuir, Freundlich, Toth, and Sips used in this study to determine the correct fit mo… Show more
