Scope

This part of GB/T 11213 stipulates the determination method of sodium hydroxide content in sodium hydroxide for chemical fiber. It is usually expressed in two different ways in terms of the mass fraction of NaOH: w1—total alkalinity (calculated as NaOH); W2—sodium hydroxide content (calculated as NaOH), that is, total alkalinity minus sodium carbonate content.
