“…Methylene blue, a cationic dye with molecular weight 373.90 gmol -1 , is commonly used in the textile and leather industries. In humans, methylene blue may cause hazardous effects like tachycardia, nausea, blue coloration of skin, and death of premature cells in the tissues [2]. Adsorption is the best process for textile dye effluent 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 R 2 is greater for pseudo second-order kinetics and Weber and Morris' model on intra particle diffusion best fit this adsorption by chitin.
