Quantitative determination of titanium dioxide in cellulose acetate spinning solutions

Conclusions A photometric method for determining the titanium dioxide content of cellulose acetate spinning solutions has been developed.The proposed method increases the accuracy and reproducibility of the results and shortens the time for analysis by a factor of two.The use of this new method significantly improves working conditions and raises safety technique.Translated from Khimicheskie Volokna, No. 6, pp. 54–55, November–December, 1989.
