Conclusions

The spectrophotometric behavior of heteroligand chromazurol S-Fe(III)-OP-10 complexes has been investigated over a wide range in pH values. It has been found that the maximum optical density is attained at pH 7.0 ± 0.1; thereupon the sodium sulfate content should not exceed 1.5% by wt.

A photometric, nonextractive method has been developed for determining the OP-10 content of technological solutions from the manufacture of Vinol fibre, which permits one to obtain correct and reproducible results.
