Abstract
The possibility of using the method of direct potentiometry with copper-selective electrodes for determining the copper(II) ion content in process solutions in manufacture of cuprammonium fibres was investigated. The pH region of stable operation of copper-selective electrodes and a method for performing measurements in the entire pH range of the solutions was proposed. The described method can be used for determining the copper(II) ion content in the presence of the components of the process solutions in manufacture of cuprammonium fibres.
