| Abstract: | Textile companies based in Constantine, Algeria, produce a profusion of colored waste such as DR 81, mainly from CG-H3G. These dyes are very toxic to residents. The main objective of this research is to mitigate the effect of these dyes using the dynamic fixed-bed bioadsorption method, using a natural biomaterial called cockle shell material (CS), which acts as a bioadsorbent. The experimental objective of this research is to apply the fixed-bed column adsorption method on a binary mixture of two dyes: Cibacron Green H3G (CG-H3G) and Direct Red 81 (DR 81). Examination of CS using the FTIR, SEM-EDX, and BET revealed that calcium carbonate predominated, with a preference for application as a bioadsorbent. Parametric analysis of various factors such as bed height (3–7 cm), feed rate (5–10 mL/min), and dye concentration in the binary mixture (20–120 mg/L) shows that the ability to adsorb dyes in the binary mixture increases with increasing concentration, flow rate, and bed height between 3 and 5 cm. Analysis of selectivity DR 81 and CG-H 3 G in the binary mixture suggests that the dye DR 81 has a greater selectivity than CG-H 3 G during the fixed column adsorption process. Kinetic data indicate that the adsorption models of DR-81 and CG-H3G dyes can be anticipated through the kinetic models of Thomas and Yoon-Nelson (R2 > 0.89). Observing the single and binary systems, it is found that the adsorption capacity of DR 81 in the binary system is slightly higher than in the simple system. Conversely, in the binary system, contrary to the simple system, the adsorption capacity of the dye CG-H3G is reduced. Finally, the obtained results confirm that CS are capable of adsorbing textile dyes. [ABSTRACT FROM AUTHOR] |
