MODIFIKASI MORDENIT TERAKTIVASI HNO3 DENGAN AMINOPROPILTRIMETOKSISILAN UNTUK ADSORPSI ION Cu(II)
Modification of HNO3-activated mordenite (ZM) by aminopropyltrimetoxysilane (APTMS) for adsorption of Cu(II) cation has been studied. Four gram of mordenite was refluxed in 20 mL of 6 M HNO3 solution for 30 and 120 min, and produced the ZM1 and ZM2 samples respectively. The samples were then modifie...

| Summary: | Modification of HNO3-activated mordenite (ZM) by
aminopropyltrimetoxysilane (APTMS) for adsorption of Cu(II) cation has been
studied. Four gram of mordenite was refluxed in 20 mL of 6 M HNO3 solution for
30 and 120 min, and produced the ZM1 and ZM2 samples respectively. The
samples were then modified using APTMS by grafting methode. The samples
were characterized by Fourier Transformed Infra Red (FTIR) spectrometry and
X-ray Diffraction (XRD) to analyze �NH2 functional groups and crystallinity
respectively. The modified samples were applied for adsorption of Cu(II) cation.
Concentration of unadsorbed Cu(II) in solution was analyzed by Atomic
Absorption Spectroscopy (AAS). The reaction kinetic and isotherm model were
also studied.
The results showed that Si/Al ratio has increased from 4.6 for ZM to
14.7 for ZM1 and 18.0 for ZM2. The success of grafting process was indicated by
the FTIR spectra which shown by the appearance of peak at wave number of
2939 cm-1 for streching vibration of �CH2 and 1573 cm-1 for bending vibration of
�NH2. The adsorption capacity of ZM |
