Abstract

This research aims to study the bio-adsorption process of two dyes, Cibacron Green H3G (CG-H3G) and Terasil Red (TR), in a single system and to bring them closer to the industrial textile discharge by a binary mixture of two dyes (TR+CG-H3G). The Cockle Shell (CS) was used as a natural bio-adsorbent. The characterizations of CS were investigated by Fourier transform infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and Brunauer–Emmett–Teller (BET). The adsorption potential of Cockle Shells was tested in two cases (single and binary system) and determined by: contact time (0–60 min), bio-adsorption dose (3–15 g/L), initial concentration (10–300 mg/L), temperature (22–61°C) and pH solution (2–12). The study of bio-adsorption (equilibrium and kinetics) was conducted at 22°C. The kinetic studies demonstrated that a pseudo-second-order adsorption mechanism had a good correlation coefficient (R2 ≥ 0.999). The Langmuir isotherm modeling provided a well-defined description of TR and CG-H3G bio-adsorption on cockle shells, exhibiting maximum capacities of 29.41 and 3.69 mg/g respectively at 22°C. The thermodynamic study shows that the reaction between the TR, CG-H3G dyes molecules and the bio-adsorbent is exothermic, spontaneous in the range of 22–31°C with the aleatory character decrease at the solid-liquid interface. The study of selectivity in single and binary systems has been performed under optimal operating conditions using the industrial textile rejection pH (pH = 6.04). CG-H3G dye is found to have a higher selectivity than TR in single (0–60 min) and binary systems with a range of 6–45 min, as shown by the selectivity measurement. It was discovered that CS has the capability to remove both CG-H3G and TR dyes in both simple and binary systems, making it a superior bio-adsorbent.
