Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
A new type of inorganic flocculant, poly silicon boron ferric zinc sulfate (PSBFZ), was synthesized from sodium silicate, ferric sulfate, zinc sulfate and sodium tetraborate by co polymerization. Its structure was characterized by FTIR, XRD, suggesting that PSBFZ is a complex compound with mainly boron-ferric-zinc-silicon polymeric species rather than a simple mixture of raw materials. Comparative flocculation behaviors among polyaluminium chloride (PAC), polyferric sulfate (PFS), poly silicate ferric (PSF) and PSBFZ were explored to treat practical wastewater, such as dyeing and printing wastewater, landscape wastewater and landfill leachate. The results demonstrate that PSBFZ exhibits the best flocculation performance. Under the optimum conditions, the removal rate of COD is up to 92.2%, 88.1% and 67.4% respectively. The removal rate of chromaticity from dyeing and printing wastewater and landfill leachate achieve 95.4% and 90.1% while the removal rate of turbidity for landscape wastewater is up to 99.3%.
