Pemanfaatan Limbah Cangkang Udang Penaus monodon sebagai Adsorben Kadmium(II) dalam Medium Air
ABSTRACT: Utilization of
shrimp shell has been optimum so that in this research preparation of adsorbent
chitosan from shell of shrimp (Penaus monodon) as raw materials for cadmium(II)
adsorption was carried out. The chitin was made by the deproteination,
demineralization; chitosan was prepared by chitin deacetylation. This work was
started with Infra Red Spectroscopic identification of functional group.
Percentage of deacetylation was determined also by Infra Red Spectroscopy.
Contant of nitrogen was determined by Kjeldhal method. The isotherm adsorption Langmuir
model was employed for the determination of the energy and the capacity in
adsorption. Result showed that chitosan could be isolated from shrimp shell
waste with % deacetylation degree of 79.80 and % nitrogen 7.11. Cadmium(II) was
chemically adsorbed on chitosan involving energi adsorption of 32.27 kJ/mole.
Adsorption capacity of cadmium(II) was 6.35 x 10-5 mole/g. The constant
adsorption rate k, was 0.91 x 10-3 s-1 and equilibrium adsorption desorption
are K = 10.28 x 103. The ability adsorption of chitosan in real waste has the
efficiency of 90%.
