Abstract

Modification of chitosan by p-t-butylcalix[4]arenes has been conducted using a nucleophilic subtitution reaction between chitosan, p-t-butylcalix[4]arenes and N,N-diisopropyl carbodiimide (DIC) in reagent dichlorometane at room temperature and under nitrogen atmosphere. Analysis structure of the chitosan-p-t-butylcalix[4]arenes is determined with spectrophotometer Fourier Transform Infra Red (FTIR) and X-ray diffraction. The melting point, surface area and morphological analysis are also conducted on the prepared materials. The prepared chitosan- p-t-butylcalix[4]arenes is white brown powder with melting point of 238 ºC. The FTIR spectrum shows a peak at 3346.50 cm-1 that indicates the presence of the N-H bonds of secondary amine. The diffraction patterns shows the presence of charge and shift in 2 .It indicates that the modification proceed successfully. The result of surface area analysis shows that chitosan-p-t-butylcalix[4]arenes is macroporous material with average of pore radius of 673.6 Å and the surface area of 16.352 m2/g. SEM analysis shows that chitosan-p-t-butylcalix[4]arenes also confirm that the materials has porous surface.
