Chitosan was prepared from prawn shell (Fenneropenaeus indicus) and squilla
(Oratosquilla nepa) and quality characteristics such as moisture, ash, viscosity and degree of
deacetylation were determined. The efficacy of the prepared chitosan to remove heavy metals
when directly added to water samples at 1% level was assessed. Water samples with the addition
of known quantities of lead, zinc, cadmium, copper and iron and water samples collected from
different locations in Vembanad Lake were used in this study. Significant reduction in the
concentration of heavy metals was observed after treatment with chitosan. Chitosan from prawn
shell was found to be more effective in the removal of heavy metals from water. Treatment with
prawn chitosan removed 68% cadmium from spiked samples, whereas squilla chitosan removed
37%. In the case of water samples collected from Vembanad Lake, treatment with chitosan from
prawn shell removed approximately 50% of cadmium and the same treatment resulted in removal
of lead to non-detectable levels in all the samples.
