Abstract

This paper has researched on the adsorption of Ni in water using Laminaria japonica and Undaria pinnatifida. The dependence on pH and nickel concentration of the adsorption was studied. Batch experiments results showed that the adsorptive capacity of Laminaria japonica and Undaria pinnatifida was 2.933mg/g and 0.985 mg/g of adsorbent. The Langmuir model was used to describe the adsorption equilibrium of nickel on Laminaria japonica and Undaria pinnatifida. The Langmuir constants for adsorption of Ni on Laminaria japonica and Undaria pinnatifida were determined.
