Abstract

The disposal of textile effluent, is responsible for serious human health concerns and above all environmental concerns to all kind of species. This indicates that there is immediate and urgent need of emerging, efficient with sustainable recycling technologies. In this paper, banana exocarp as agriculture based waste, in terms of substrate was utilised as major raw material. The extracted cellulose from the substrate with homogeneous acetylation process, transformed into cellulose acetate (CA). Phase inversion method was used to prepare dense CA membranes. Thereafter graphene nanoparticles were incorporated in CA, which improvise affinity towards heavy metal ions, stability to dispersion and even membrane hydrophilicity. The experimental and analytical methods such as FESEM with EDS, XRD, FTIR and Contact Angle used compressive characterisation of fabricated membrane. The observations from all this analysis evaluated the structural, thermal and surface properties of casted membrane. This designed and formulated nanocomposite membrane were applied for recycling of textile effluent instead conventional process. The efficiency and performance of nano filtration was assessed for Ni²⁺, Fe²⁺, Zn²⁺ and Cu²⁺ ions. The enhanced membrane selectivity added advantage through adsorption sieving mechanisms and surface complexation with metal ions. In comparison with conventional CA membranes, the graphene nanocomposite CA membranes confirmed enhancement in removal efficiency of heavy metals from waste water, achieving rejection rates of up to approximately 93% for Ni²⁺ and Fe²⁺. The combined effect of CA and Graphene attributed to the improved version of Cellulose Acetate Graphene Nanocomposite Membrane. Overall, the findings indicate that cellulose acetate membranes derived from banana exocarp and modified with graphene offered a sustainable and effective solution as emerging treatment technology. In addition, these membranes exhibited superior antifouling characteristics and maintained stable permeate flux during operation.
