RESPONSE SURFACE METHODOLOGY APPLIED FOR ZINC REMOVAL FROM AQUEOUS SOLUTIONS USING SPHAGNUM PEAT MOSS AS SORBENT
The efficiency of Zn (II) removal from aqueous solutions was investigated using Sphagnum moss peat as adsorbent. A 23 full factorial central orthogonal design was carried out in order to achieve the best conditions of the sorption of Zn (II) on peat. The combined effect of initial concentration of Zn (II) in aqueous solution (C0, mg/L), peat dose (G, g/L) and pH was studied and optimized using Response Surface Methodology (RSM). The optimum values
