Inorganic contaminants present in waste streams may be removed by one of three methods, viz. physical, chemical or biological. Chemical and physical techniques have traditionally been employed to remediate such streams. Biological structures such as bacteria, fungi, algae and others of higher structural complexity are potential adsorbents due to their abundant presence in the environment.Biosorbents derived from the biomass of marine algae have shown high uptake capacity for heavy metals.Biosorption, an inexpensive and reliable method to remove copper,zinc,nickel,chromium ions from solution. Dry sea weeds biomass used as adsorbents mainly because of its low cost and high metal binding capacity. In this work, the basic investigation is removal of copper and nickel ions from aqueous solution by Sargassum sp.Effects of algal biomass and medium pH on the metal ions were determined and optimized. Under the optimal conditions of the corresponding metal ions, the algal Cu²⁺ and Ni²⁺ were 51.11 and 63.54 mg/g respectively. The kinetic study revealed that the adsorption of Cu²⁺ and Ni²⁺ by Sargassum sp. fitted the Langmuir isotherm.
