Method for the determination of quu00ecmicas species in a sample of liquor in alkaline pulping of wood containing boron and determination of parameters of pulping of wood in a sample of liquor Share of wood containing alkaline boron.
Method for the determination of quu00ecmicas species in a sample of liquor in alkaline pulping of wood containing boron and determination of parameters of pulping of wood in a sample of liquor Share of wood containing alkaline boron.
Method of determination of quu00ecmicas species in a sample of liquor in alkaline pulping of wood containing boron and determination of parameters of pulping of wood in a sample of liquor of Po.Lpau00e7u00e3o alkaline wood containing boron.Chemical species (for example, metaborate, carbonate, hydroxide and sulfate) in a sample of liquor of wood pulping alkali containing boron.Are determined quantitatively (I) subjecting a first portion of the alu00edqu00b3ota sample to an analysis of titration acid primary to obtain multiple points of equivalence in different exp.And their pH; (II) subjecting to a second portion of alu00edqu00b3ota sample to an analysis to determine the quantitative presence of boron or sulfide ions therein, and then (III) determiningIf the presence of the sample to at least one chemical species.The parameters of wood pulping may, thus,To be determined on the basis of the quantitative presence of chemical species to assist in the process and / or to control the operation quantity of pulping of wood.
