Abstract: The reed pulping black liquor is used as a sample. Researches of (1)
combined effect of ultrasound(US)/polyferric sulphate(PFS)/hydrogen peroxide
(H_2O_2); (2) effects of the horn tip
areas; (3) effect of dose of PFS were carried. Extrapolation of these
experiments indicated treatment results are possibly related to complex
chemical compositions in the reed pulping black liquor.
