The purpose of this study is to investigate the optimum contact time and adsorption
capacity of adsorbent through the batch technique in multimetal solution of Fe/Mn. The
amount of metal ions being adsorbed was calculated by using Atomic Absorption
Spectrophotometer (AAS) based on the difference between the concentration of metal
ions before and after adsorption. In the Fe/Mn system optimum adsorption for SG and
HMS occurred at 60 and 30 minutes of contact time, respectively. Adsorption of Fe/Mn
by SG adsorbent is in compliance with Freundlich isotherm pattern where the value of
KF is 141.49 L/µmole for the Fe(III) and 0.20 L/µmole for Mn(II). Adsorption of Fe/Mn
solution by using HMS adsorbent was in compliance with Freundlich isotherm model for
Fe(III), while the adsorption of Mn(II) in the same solution complied with the Langmuir
isotherm model. Fe(III) ion has a KF value of 0.34 L/µmole. If it was calculated using the
Langmuir model, the adsorption capacity and adsorption energy for Fe(III) adsorption on
HMS were 279.25 mg/g and 11.47 kJ/mole, respectively. Whereas for Mn(II), the
adsorption capacity was 8.32 mg/g and the adsorption energy was 17.97 kJ/mole.
