摘要：The aim of the present investigation was to study the effects of four different process parameters such asinitial lead concentration (10 to 30 mg L-1), pH (3.5 to 6.5), dosage concentration (10 to 50 g L-1) and temperature (200C to 40 0C) using activated carbon derived from Palm kernel cake as the adsorbent for the removal of hazardous leadmetal from aqueous solution. Doehlert Design of Response Surface Methodology was employed to model thebiosorption process by a second order quadratic model. Optimization of the response surface model predicted a 91.80%maximum removal of lead at the optimum process conditions of initial lead concentration: 21 mg L-1, pH: 4.6,adsorbent dosage: 26 g L-1 and temperature: 32 0C. The validation experiment carried out at the optimum processconditions confirmed the predicted values. The results demonstrated the potential use of activated carbon of palmkernel cake as a novel adsorbent for the optimal removal of lead using 4-variable Doehlert design.
