Title : Hydrogel based on hydroxyethyl cellulose extracts from date palm fronds containing zinc oxide nanoparticles for textile dyes degradation and antimicrobial purposes
Abstract:
The rising global worry over water body harmful bacteria and poisonous dyes need an urgently effective cleanup plan. Using hydroxyethyl cellulose (HEC), which was synthesized from extracted from date palm fronds using alkaline peroxide extraction technique. ZnONPs were created in this study. UV-vis was utilized to check the form of HEC, which was employed as a capping gent, and showed the existence of an absorption peak at 364 nm. In the meanwhile, TEM was used to demonstrate the ZnONPs' good distribution. An effective hydrogel that crosslinked with calcium chloride (CaCl2) was then created by blending ZnONPs with a solution made of HEC and sodium alginate (SA). The effective synthesis of zinc oxide nanoparticles@hydroxyethyl cellulose/sodium alginate (ZnONPs@HEC-SA) hydrogel was verified using FTIR, SEM-EDX, and swelling ratios. The current study was expanded to examine the effectiveness of ZnONPs@HEC-SA and HEC-SA hydrogel in eliminating Crystal Violet (CV) dye from water. The adsorption properties of the hydrogel were evaluated using a range of factors, including different pH levels, contact times, and ZnONP concentrations. The photocatalytic degradation efficiency of ZnONPs@HEC-SA hydrogel under UV light exposure was also evaluated. Such potential hydrogel materials' antimicrobial properties were examined. Our results demonstrated the improved adsorption capabilities of the ZnONPs@HEC-SA hydrogel, which after 105 minutes totally destroyed (100%) the CV dye at higher ZnONPs@HEC-SA dosages and shorter irradiation times. Furthermore, the hydrogel showed remarkable reusability for dye removal across a number of cycles, indicating that it may find practical applications in wastewater treatment. Comparing ZnONPs@HEC-SA to HEC-SA hydrogel, the results showed a strong antibacterial impact. This study demonstrates the effectiveness of ZnONPs@HEC-SA hydrogel as an adsorbent and photocatalyst for the removal of organic dyes from contaminated water sources that have antimicrobial properties.
