- W2390907761 abstract "An inorganic composite flocculant of Fe(Ⅲ), Mg (Ⅱ) and Al(Ⅲ) (PFMAS) was optimally prepared and used to pretreat landfill leachate, in which H2O2 was used to oxidize Fe(Ⅱ) to form Fe(Ⅲ), and then Fe(Ⅲ) polymerized with Al(Ⅲ) and Mg(Ⅱ). The results showed that the removal rate of COD of landfill leachate was the highest when the ratio of Fe (Ⅲ), Mg (Ⅱ) and Al (Ⅲ) was 4:0.07:1. The addition of flocculants and the pH value of landfill leachate had significant effects on the flocculation process. The optimal flocculating effect could be achieved with the addition of PFMAS at around 95 mL/400 mL leachate, pH at 8.0. In addition, the microcosmic crystal structure of PFMAS was observed by using scanning microscope, and Fe (Ⅲ), Mg (Ⅱ) and Al (Ⅲ) were found tightly combined and long macromolecular chains were constructed. FTIR results showed that PFMAS was a kind of inorganic macromolecular flocculants relying on -OH bonding." @default.
