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.
Hydroxyl-terminated hyperbranched polymer (HPAE) and ferric sulfate were as material, hyperbranched polymer flocculant was prepared. The optimal conditions were that m(HPAE): m(Fe2(SO4)3)=2:l, pH was 2, temperature was 30°C and time was 18h. Its structure was characterized by IR and Hl-NMR , Moreover, it was applied in flocculating precipitation of oil and gas waste drilling fluid. The results showed that HPAE-F had good flocculation effect on waste drilling fluid. The chromaticity removing rate of supernatant fluid was 95%, and transmittance was 96.5%.
