Abstract

The current study was undertaken to estimate the effectiveness of the brown algae Sargassum latifolium in removal of Ni2+ and Pb2+ ions from metal solution by adsorption as alternative low-cost adsorbents. Laboratory batch examination was conducted to estimate the influence of contact time, pH, initial Ni2+ and Pb2+ ions concentration, temperature and adsorbent dose on adsorption efficiency. The highest metal removal was obtained under condition of  pH 7&6, temperature 25 & 30 oC , contact time of 5 & 60 min for Ni2+and Pb2+ ions respectively, and optimum amount of 2.5 g with initial metal ions concentration of 10 mg L-1.Different isotherm models, namely Langmuir, Freundlich, Temkin and Dubinin–Radushkevich were used to analyze the investigational data, and the models parameters were evaluated. The maximum removal capacities (Qmax) estimated by Langmuir isotherm were 0.276 and 0.171 mg g-1 for Ni2 +and Pb2+, respectively. Furthermore, the kinetic studies proved that alga has poor fit by pseudo first-order model while they have a good fitting with pseudo second-order model. In addition, the applications of alga to remove pb2+ions from seawater and wastewater were investigated under optimization conditions.
