PENGARUH HIDROKSIAPATIT TERHADAP PEMBENTUKAN KOMPOSIT KITIN/KITOSAN DARI LIMBAH KULIT UDANG
Abstract: The effect of hidroxyapatite toward chitin/chitosan
composite’s formation from waste shrimp shell
had been conducted.
Samples were analyzed
byFTIRequipment(Fourier
Transform Infrared), SEM(Scanning Electron
Microscopy) andTG-DTA (Thermal
Gravimetry-Different thermal Analysis). FT-IR spectra show the peaks of
the carbonyl group on λ = 1557,69 cm-1 indicated acetyl group on composite. SEM image show the looked like long
needle while on another composition formed agregat. ResultTG-DTA
analysis showed the
stability thermal formed
at addition on
variation 1 gram of hydroxyapatite
and was proved by stable weight decrease
at every stage. The increasing of
hydroxyapatite on sample
can increase the
thermal stability of
composite chitin/chitosan/hydroxyapatite.
