摘要： A method for determining simultaneously from an oxidized black liquor sample an amount of sulfide, an amount of total dissolved solids, and an amount of effective alkali present in the sample, wherein the sulfide amount, the total dissolved solids amount, and the effective alkali amount are determined by subjecting the sample to attenuated total reflection (ATR) ultraviolet/visible (UV/V) spectroscopy over a wavelength of from about 190 to about 500 nm. Data from analyzing oxidized black liquor samples, and from analyzing one or more black liquor samples which may be subjected to black oxidation, may be used in a black liquor oxidation (BLOX) system for monitoring and/or controlling sulfur emissions from a kraft process.

摘要： A system and method for rapidly determining the pulp kappa number through direct measurement of the potassium permanganate concentration in a pulp-permanganate solution using spectrophotometry. Specifically, the present invention uses strong acidification to carry out the pulp-permanganate oxidation reaction in the pulp-permanganate solution to prevent the precipitation of manganese dioxide (MnO2). Consequently, spectral interference from the precipitated MnO2 is eliminated and the oxidation reaction becomes dominant. The spectral intensity of the oxidation reaction is then analyzed to determine the pulp kappa number.
