![]() ![]() Based on the D-R model, the adsorption of AY25 dye ontoĬhitin is via chemisorption. Our results show the highest correlation with the Langmuir model,Ĭonsistent with the fact that chitin contains both a monolayer and homogeneousĪdsorption sites. Isotherms were analyzed by utilizing the Langmuir, Freundlich,ĭubinin-Radushkevich (D-R) and Temkin isotherm models at 23℃, with dataĬollected by using various initial dye concentrations with different chitinĭosages. Order adsorption mechanism is predominant, and the overall rate of the dyeĪdsorption process is therefore controlled by an adsorption reaction. Order, pseudo-second order, and intraparticle diffusion equations toĭetermine the rate controlling step. The adsorption kinetics was modeled using pseudo-first The suitability of chitin extracted from waste crab legs as an adsorbent for Hence, it is important to find simple, efficient,Īnd inexpensive ways to remove these dyes from wastewater. ![]() Effluents from such industries are major sources of water pollution.
