| description | The utilization of orange (citrus nobilis var. microcarpa) waste for the
adsorption of Zn(II) has been examined in this study. The orange waste was
modified through saponification using NaOH and Ca(OH)2 to form saponified
orange waste of Na (SOW-Na) and saponified orange waste of Ca (SOW-Ca).
The synthesis of SOW-Na and SOW-Ca was done by adding respectively the
solutions of NaOH and Ca(OH)2 to the orange waste to achieve the solution
medium pH 10, 10.5, 11, 11.5, 12 and 12.5. Characterization of SOW-Na and
SOW-Ca was carried out using Fourier Transform Infrared Spectrophotometry
(FTIR).
The result showed that the highest ion exchange capacity of SOW-Na was
achieved at pH 12.5, i.e. 1.53 mol/Kg, while SOW-Ca was at pH 11.5, i.e. 2.39
mol/Kg. Adsorption of Zn(II) on both SOW-Na and SOW-Ca was optimum at
medium pH 6 and it followed pseudo second order with adsorption rate constant
were 1.02·10-3 mM-1·min-1 and 2.40·10-3 mM-1·min-1, respectively. Adsorption of
Zn(II) on both adsorbent fitted well to Langmuir isotherm with capacity 45.94
mg/g for SOW-Na and 41.06 mg/g for SOW-Ca. By using biner solution Zn(II) �
Pb(II), the abilities of SOW-Na and SOW-Ca in adsorbing Zn(II) decreased
significantly, while in biner solution Zn(II) � Cd(II) the abilities of the both
adsorbents in adsorbing Zn(II) were affected insignificantly. |
