Response surface methodology for prediction of Pb(II) adsorption characteristics

Monal Dutta, JayantaKumar Basu

In the present investigation a half-fraction central composite design had been applied for prediction of Pb(II) adsorption capacity on the surface of microwave assisted activated carbon. For this purpose, five input variables such as, solution pH, initial concentration, adsorbent concentration, temperature, contact time and one output variable, Pb(II) adsorption capacity had taken into consideration. The optimum adsorption conditionwas found to be pH: 6, initial concentration: 120mg/L, adsorbent concentration: 1.5 g/ L, temperature: 20 °C, time: 80 min.
