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 novel multi-branched non-ionic polyacrylamide was synthesized using ceric ammonium nitrate and pentaerythritol as redox initiation system at 47°C in aqueous medium. The synthesis conditions of multi-branched polyacrylamide were studied and the stability of PAM aqeous solution was determined based on their intrinsic viscosity. The new polyacrylamide had a better stability when pH value was under 12. Flocculation properties of the product were evaluated in terms of transmittance, removal of organic contaminant and solid suspending substances. Influences of pH, concentration of PAM and PAM/PA on flocculation efficiency of PAM were examined. The flocculating effect was comparatively ideal when it combined with inorganic flocculant polymeric aluminum in oil wastewater, and the transmittance of wastewater was over 95%.
