| Abstract: | Hydroxyl hyperbranched polymer(HPAE) ends possess many active groups.A new polymer flocculant(HPAE-F) was prepared by loading Fe~(3+) on it.The optimal conditions were:m(HPAE): m[Fe_2(SO_4)_3]= 2:1,pH = 2,reaction temperature 30℃,reaction time 18 h.IR,UV and ~1H NMR were used to characterize the structure of HPAE-F.Its heat stability was tested by thermal analysis. It was applied in flocculating settling of oil and gas waste drilling fluid and the results showed that HPAE-F had good flocculation effect on waste drilling fluid,with the colar removing of 95%from the supernatant fluid and luminousness of 96.5%. |
