Abstract

Oxidized white liquor is heat treated to increase the concentration of PSUV measured at 285 or 286 nm or PSVIS measured at 416 nm and the PSUV/PSGR or PSVIS/PSGR ratio, whereby the content of active polysulphide in the total polysulphide is increased which active polysulphide can be exploited to increase pulp yield in Kraft pulping.
