| Abstract: | Conclusions A procecure has been developed for the photometric determination of the aluminum sulfate content of a mixed zinc-aluminum-containing precipitation bath in viscose manufacturing, using the bifunctional organic reagent chromazo-BRZ.The procedure is highly selective, simple, and rapid. The relative mean-squared deviation (variation coefficient) is 2.4% for an aluminum sulfate concentration of 20–30 g/dm3.The authors express his thanks to N. N. Basargin, doctor of chemical science, and his co-workers in the analytical division of the IGEM, Academy of Sciences of the USSR, for consultation and help in this work.Translated from Khimicheskie Volokna, No. 6, pp. 52–53, November–December, 1989. |
