The major leading fact for environmental issue is due to pollution. Water pollution is basically the effective cause herewith due to pollutants released from industries, battery waste, e-waste etc. To eradicate the health issues in relation to environment is observed when heavy metals are removal from wastewater to some extent. Lead is one of the highest toxic metal among others. In the present work, the biosorption of lead from wastewater using marine algae ulva lactuaca is carried away. biosorption is considered as an effective process. The Optimization of biosorbed lead under the experimental process is predicted by the help of the 3-D RSM designing. CCD (central composite design) is a 3 D design used to illustrate the optimum conditions according to the experiment performed and support to justify the final results obtained as an optimum values of pH 3.67, dosage 12 g/L, concentration 30.01 mg/L, Temperature 318K and % removal and Desirability are shown best as 94.9566 % and 0.808 respectively.
