Modification of snail shell for the removal of remazol brilliant blue dye from wastewater

There are many toxic and harmful dyes that must be disposed of by the use of desiccant materials. These materials remove these dyes from aqueous solutions, and among these dyes is Remazol Brilliant Blue dye. The percentage of removing Remazol Brilliant Blue dye from its aqueous solutions was (99.3120 %). The best conditions for this study were also studied from the (equilibrium period, adsorbent mass, PH, temperature, and application “Langmuir, Freundlich and Temkin” Models were examined. The experimental isotherm data demonstrated that the Freundlich and Temkin equation and those results are in good accord to assume the form (S-curve) based on Giles categorization, Additionally, it is in conflict with Langmuir equation. The (ΔS, ΔH, ΔG) thermodynamic functions were determined and described in terms of the adsorbant’s chemical makeup on average.
