Conclusions
The metrological characteristics of methods of determining chloride ion using the chloride-selective ÉM-C1-01 electrode, direct potentiometry, or potentiometric titration with AgNO3 or Hg2(NO3)2 solutions have been examined. The methods are characterized by accuracy and reproducibility of results.
The possibility of using the ÉM-C1-01 electrode for contr 1 of technological solutions containing from 0.5 to 6% by wt. chloride ion in the manufacture of aromatic polyamide fibres has been demonstrated.
