Preparation and characterization of chitin from Arabian Gulf shrimp

الملخص EN

Chitin was chemically isolated from shrimp shells, under various and characterized.

Utility of isolated chitin as anion exchange for removing, the effect of sodium hydroxide, hydrochloric acid concentrations, reaction duration and temperature, liquor ratios and antifoam effect were examined.

The characterization of prepared chitin were performed through nitrogen percent, ash content, moisture and Fourier transform infrared data.

The capability of the use of prepared chitin for serving as anion exchange from aqueous solutions was examined.

Experiments were performed as a function of dye concentration, pH and the time of equilibrium.

It was shown that the adsorption capacity of chitin was high for the two investigated dyes.

These tests showed that the prepared chitin contain 6.8 N %, ash content, 0.33 %, weight yield percent, 19.2 % and moisture 8.7 % and characterized by a global efficiency superior to decontamination of water containing acid dye.
