Adsorption behavior of disperse orange 30 on polyester fabric

In this study, the adsorption behavior of disperse orange 30, including the adsorption isotherms, Kinetic adsorption and thermodynamic parameters on polyester products at different temperatures (90, 100, 110 ° C) were examined. To determine Adsorption Equation type, Nernst, Langmuir and Freundlich Adsorption Isotherms were used. Results indicate that the most Correlation Coefficient value belongs to Nernst’s Adsorption Isotherms. To determine Kinetic adsorption equation type, pseudo first order and pseudo second order equations were used. And studies attribute the best and highest Correlation Coefficient value to the pseudo second order equation. Thermodynamic parameters such as enthalpy, entropy and standard affinity were studied; negativity of these parameters is the evidence of adsorption process’s being exothermic.
