Fibre Chemistry Aims and scope

Conclusions

In the accelerated method of determining the free alkali content of viscose, the operations of separating the cellulose xanthate and of oxidizing the sulfur-containing impurities with potassium ferricyanide are eliminated.

Results from determinations by the accelerated method essentially coincide with the data obtained by calculation.
