Cyanide is highly toxic, with widespread industrial use posing serious environmental risks. Effective materials for detecting and filtering cyanide from water are urgently needed. This study introduces a novel approach utilizing Cu-TCPP (TCPP = o-tetra(4-carboxyphenyl)porphine) metal-organic nanosheets (MONS) embedded in thin-film composite membranes, offering multifunctional solution detection filtration. Ultrathin MONs were synthesized using surfactant-assisted method featuring accessible metal centers that enhance interaction detection. The developed by modifying cellulose acetate (CA) MONs, demonstrated exceptional performance removal. 6% Cu-TCPP/CA membrane exhibited 2.3-fold increase pure permeability achieved removal efficiency of 94.68%, significantly outperforming the pristine 0% (Pure Water Permeability (PWP) 380.83 L m-2 h-1 bar-1; CN- 5.01%). first report describing technique literature. In addition to its efficiency, showed remarkable capabilities, calculated limit 1.76 × 10-7 M, surpassing World Health Organization (WHO) United States Environmental Protection Agency (EPA) safety standards levels water. Additionally, bioimaging agent excellent cell viability, deployed detect MiaPaCa-2 cells, concentrations as low 0.1 ppm.
