Efficient Removal of Organic Dye from Aqueous Solution Using Hierarchical Zeolite-Based Biomembrane: Isotherm, Kinetics, Thermodynamics and Recycling Studies

Bio adsorbents have received tremendous attention due to their eco-friendly, cheap and non-toxic nature. Recently, bio-adsorbent-based membranes been frequently employed for water treatment. The work reports the preparation of a novel adsorbent membrane from hierarchical zeolite, polyvinyl alcohol, carboxymethyl cellulose agar. fabricated was characterized spectroscopically microscopically with several techniques such as XRD, UTM, TGA, optical microscopy FT-IR, well contact-angle studies. result showed that hierarchical-zeolite-loaded is superior in terms thermal stability, mechanical properties surface roughness. investigated its efficiency removal Congo red dye aqueous conditions. influence pH, temperature, contact period initial concentration zeolite loading on adsorption process are also explored. results highlighted maximum sorption property agar/zeolite/carboxymethyl cellulose/polymer biomembrane found be higher (15.30 mg/g) than powder (6.4 mg/g). isotherms kinetic parameters were via Langmuir, Freundlich pseudo-first order, pseudo-second order intraparticle diffusion model, respectively. fitted both considered isotherms, whereas kinetics. thermodynamic parameter, ?G at 303 K, 313 K 323 ?9.12, ?3.16 ?0.49 KJ/mol, further explores antibacterial efficacy prepared reusability.
