Eco-Friendly Adsorption of Methyl Red Using Biodegradable Sea Shells: An Isotherm Approach

Organic dyes have been identified as significant water contaminants. The use of low-cost, easily available, highly effective, and non-toxic adsorbents has been examined as an appropriate alternative to the available expensive techniques for removing dyes from effluent. This research aimed to investigate the utilization of Sea shells (SS) as an adsorbent material for removing Methyl Red (MR) dye from aqueous solutions. The influence of several factors: (contact time, pH, Temperature) on the adsorption ability of MR dye was evaluated. The results indicate that The optimum conditions were found: pH 3, 45 min contact time, and 30o C. Fourier Transform Infrared spectroscopy (FTIR) evaluates the chemistry of SS. The isotherm of Langmuir (R2 = 0.9531) was a better fit than the isotherm of Freundlich (R2 = 0.921) and Temkin isotherm (0.928) for data. The maximum monolayer adsorption efficiency was measured at 0.5 mg/g. The study found that SS is an excellent and inexpensive adsorbent for removing MR dye from solutions.
