ABSTRACT: Chitosan is
polycationic in acidic media and can interact with negatively charged species
such as tripolyphosphate (TPP), which is a nontoxic crosslinking agent. The
synthesis of TPP crosslinked chitosan was perfomed by reacting TPP solution (pH
3) with chitosan solution. The aim of this study was to prepared and
characterize the crosslinked chitosan-tripolyphosphate samples.
Characterization included determination of water and ash degree, moreover
crosslinked chitosan-tripolyphosphate powder characterize with FTIR and XRD
spectroscopy. The result showed that process efficiency of crosslinked
chitosan-tripolyphosphate was 88.49%, with degree of water and ash were 25.70
and 16.72%, respectively.
Keywords: chitosan,
