KINETIC STUDY OF THE ADSORPTION OF THE REMOVAL OF BROMO CRESOL PURPLE FROM AQUEOUS SOLUTIONS

This study was carried out to estimate the kinetic behavior of adsorption of bromo cresol purple from aqueous solution by using low cost of natural materials (sea grasses). The calculations of adsorption system were evaluated according to Langmuir adsorption and Freundlich isotherms. Also, the removal percentage of the studied dye was calculated. The results recorded that the values of RL were found to be less than (1) and slightly high than (0) value ≈ 0.014 indicating the favorable adsorption of the selected dyes on the sea grasses. On the other side the study recorded that the adsorption isotherms are harmony with the Freundlich concept of adsorption. According to the values which obtained from the isotherms in this study of bromo cresol purple. The adsorption process follows the first order reaction.
