| Abstract: | This study introducesFraxinustree leaves as a new, efficient biosorbent of As(III). A suitable response surface was achieved by running a central composite design. Simultaneous optimization of both responses (R% andq) was carried out and 67% of the goal of desirability function was attained. The results obtained for simultaneous optimization areR = 70% andq = 80.6 mg g−1with 67% desirability inm = 600 mg L−1wheres = 0.10 g and pH = 3.9. Langmuir and Freundlich isotherms model were applied in explaining the sorbent–sorbate equilibrium study, and maximum capacity uptake equals 99.97 mg g−1andKL = 0.05 L mg−1has been obtained. Fourier Transfer Infra-Red (FT-IR) and kinetic results were considered to examine the functional groups involved and the adsorption mechanism. [ABSTRACT FROM PUBLISHER] |
