Combined effect of US/PFS on the black liquor of making paper.
The reed pulping black liquor is used as a sample. Researches of (1) combined effect of ultrasound( US)/polyferric sulphate (PFS)/hydrogen peroxide (H2O2); (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.
