Biological and chemical treatment
The adsorption potential of chitin, a polysaccharide found in the exoskeleton of shrimp, was evaluated using methylene blue cationic dye. Batch adsorption studies were done using a column by optimized bed height of 22.2 cm and retention time of 90 min. The alginate:chitin ratio was taken as 1:07 with 80 mgl-1initial dye concentration, and pH was maintained at 8. There was 90% adsorption of dye. Langmuir and Freundlich isotherms were studied along with the adsorption kinetics. The plots indicated that the data fitted Langmuir isotherm. The R2 is greater for pseudo second-order kinetics and Weber and Morris’ model on intra particle diffusion best fit this adsorption by chitin.
