This section specifies a method for the determination of the pH value of battery pulp paper, which is applicable to the determination of the pH value of such paper. Reference documents include QB/T 2303.1-2008 and QB/T 2303.6-2008. The principle is to determine the hydrogen ion concentration in the sample after it is leached in distillation water, expressed in pH. The required reagents include distillation water and standard buffer solution. Determination is made using an acidity meter with an accuracy of 0.01. Sampling is to be carried out as specified in the QB/T 2303.1-2008.
