Nanofibrous Membranes for Low-Concentration CrVI Adsorption: Kinetic, Thermodynamic and the Influence on ZFL Cells Viability

There is a great demand to develop different techniques for the continuous removal, immobilization, and remediation of metallic ions from contaminated water. Human contamination by could even occur ingestion seafood causing carcinogenic mutagenic activities. In this study, nanofibrous membrane poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) produced electrospinning technique coated with polyaniline (PAni) was tested removal chromium in low-concentration solutions. The viability ZFL cells (zebrafish liver cells) performed evaluate water quality enhancement after adsorption. results indicated that successfully adsorbed species (Qe= 2.44 mg/g, at pH 4.5, room temperature (RT) 24h) Freundlich model followed pseudo-second-order kinetics indicating possible chemisorption multilayers, RT [CrVI] = 5.0 mg/L. At 2.0 (24h, mg/L), around 91.64% CrVI contaminants. thermodynamic studies revealed process spontaneous exothermic. demonstrated efficiency aquatic ecosystem protection; increased 19.2% mg/L solution. Thus, study shows can be an alternative remove low concentration aqueous
