Heavy metals are perilous contaminations that may exist in marine, ground, modern and even treated waste waters. Defilement of watery situations by weighty metals is an overall ecological issue because of their poisonous impacts and their collection through the natural pecking order. Because of fast advancement of mechanical exercises lately, the degrees of weighty metals in water frameworks, which have considerably expanded after some time, will prompt unnecessary arrival of the hefty metals into nature. Thus, it's important to eliminate these metals from mechanical effluents before releasing watery squanders into condition. The present experimentation is aimed at removal of cobalt using gracilariacorticata red algae powder. The parameters varied are contact time, pH, sorbent size, dosage of sorbent, initial concentration and temperature. The kinetics studied arelagergren first order and pseudo second order. Isotherms varied are Langmuir, Freundlich and Temkin. Optimization was carried out using Artificial neural networks and response surface methodology. The results were compared and are in good agreement.
