  Abstract

The textile and chemical industries generate dyes wastewater with full of pollutants, which is very crucial to treat before discharging to the environment for public health safety. In this study, we have successfully prepared novel Cur/ANFs aerogel flms by vacuum fltration and freeze–drying method to follow the in situ modifcation of aramid nanofbers (ANFs) with natural carbohydrate polymer curcumin (Cur) to perform as an antibacterial material and adsorbent for removal of MG dye and metallic ions from aqueous media. The surface morphological properties were studied through SEM, EDS, XPS, FTIR, and XRD analysis. Further, TGA analysis shows the thermal stability of flms, while flms exhibit a moderate reduction in tensile strength upon addition of curcumin. In addition, 1.0-Cur/ANFs aerogel flm exhibits an excellent antibacterial activ ity against S. aureus and E.coli as compared to all flms. Moreover, the parameters such as equilibrium time, adsorbent dose rate (5–20 mg) at fxed MG dye concentrations were determined to adsorption capacity of flms. The results revealed that the pseudo-2nd-order kinetic model was ftted to adsorption mechanism with correlation coefcients (R2>0.90). In addition, the 20 mg adsorbent of 1.0-Cur/ANFs aerogel flm after 120 min contact time in MG dye solution have excellent adsorption capacity (93.68%) as compared to all samples. The adsorbent 1.0-Cur/ANFs aerogel flm have high metallic (Cu; 5.82%, Zn; 2.33%, Pt; 3.11%) ions removal efciency as compare to pure ANFs aerogel flm (Cu; 0.03%, Zn; 0.01%, Pt; 2.75%). Further, the fndings on reusability shows that adsorbent 1.0-Cur/ANFs aerogel flm after 5th cycle still exhibit excellent (73.08%) adsorption capacity of Mg dye without deformation as compare to pure ANFs aerogel flm (52.67%). Consequently, the inclusion of curcumin in ANFs is more suitable and cost-efective approach for removal of MG dye and our prepared 1.0-Cur/ANFs aerogel flm is a promising candidate for purifcation of water and public health safety.
