Removal of phenolic contaminants from water by in situ coated surfactant on Keggin-aluminum nanocluster and biodegradation

Recent water treatment plants require multi-process techniques to remove contaminants from aqua media. In this study, we investigate the novel, in situ coated sodium dodecylsulphate (SDS), on kegging Al-30 nanocluster as a single water treatment alternative for the removal of phenolic contaminants and suspension. FTIR, TEM-EDX and Zeta potential analysis characterized the nanocluster decoration. The resulting property was examined by emission (lambda-max) of the molecular probe, the online aggregate image of fluorescence microscopy, and mixing isochrone, fat-soluble dye solubilization. The coated media was examined as nearly resembling the hydrophobicity of 1-octanol. The elemental line scanning and mapping showed different morphologies of floc depending on the SDS concentration. The material was found to follow Brownian motion to enmesh suspended particles like a ladder, and served as entrapper for small organic contaminants by the sorbed SDS aggregate, based on their log K-O/W. About 85% and >= 95% removal archived for contaminants with the least and highest K-O/W value, respectively. The residual solutes in the supernatant were well decomposed by using a bacterial agent. One-step removal (less footprint) and ease of operation make this approach an environmentally compatible and cost-effective alternative for the large-scale treatment process. (C) 2020 Elsevier Ltd.
