From Hazardous Chrysotile and Polyamide Wastes into Sustainable Serpentine/Polyamide Nanocomposite Membrane: Fabrication, Characterization, and Environmental Application

Sustainable serpentine/polyamide nanocomposite (SP/PAM) was fabricated using malicious mining (serpentine chrysotile, SP Ctl) and industrial (polyamide, PA6) wastes via the electro-spinning technique. Before fabrication, fibrous nature of Ctl demolished through intensive grinding into nano-fractions. The successful impregnation within PA6 technique at fixed ratios precursor raw materials in dissolving agent (7.5/92.5% SP/PA wt/wt solid/solid) created an internal network structure polymer fibers by molecular self-assembly. SP/PAM showcased its prowess tackling remediation diverse dyes Fe(III) from synthetic solutions a batch system. Based on correlation coefficient outcomes (R2 ≈ 0.999), pseudo-second-order equation justified sorption data adequate way for all contaminants. In addition, intra-particle diffusion not only driving factor process. Similarly, Langmuir with maximum removal capacity (qmax) 5.97, 4.33, 5.36 mg/g MO, MB, Fe(Ⅲ), respectively, defined better than Freundlich.
