| 英文摘要 | Simultaneous removal of poorly biodegradable synthetic dyes and associated suspended particles, like a textile effluent, is a common challenge in the water treatment sector. Herein, a method based on sodium dodecyl sulfate (SDS) as a sorbet to modify fresh aggregate of polycationic nanocluster (Al-30) was developed for the simultaneous removal of dyes and suspension from the water by one-step treatment. The FT-IR, TEM and Zeta potential analysis revealed that dodecyl sulfate (DS) was favorably adsorbed onto the fresh aggregates of Al-30, which was found to follow Langmuir isotherm (R-2 = 0.988) rather than Freundlich model (R-2 = 0.726). The negative Delta G(ads)(0) (-29.3) and R-L value (0.1535), between 0 and 1, further corroborated the spontaneous SDS condensation on the Al-30 aggregates. In the treatment of dye wastewater, the target dyes and turbidity were removed more than 95% at pH 8, concomitant with DS adsorption. The linear relation between X-adm and X-bul (R-2 = 0.99) described the classical partitioning of dyes into the modified surface, which was further confirmed by TEM-EDX investigation and online fluorescence image. The simultaneous removal of concentrated dye and suspension suggests the applicability of this method for a textile and other dye wastewater treatment alternative. |
