The Application of Potentiometric Methods to Developer Analysis
Potentiometric titration methods are applied to routine developer analyses in order to simplify and speed up the operation and to minimize the human error arising from judgment of color change end points, etc. A brief theoretical treatment of potentiometric titrations is included, and new tests for elon, hydroquinone, and carbonate are outlined. Previously published methods for bromide and sulfite are also included. Detailed procedure outlines are included along with a discussion of the problem of pH vs. the alkali content of a developer. A glossary showing stepwise procedure operations required to accomplish the analyses has been compiled along with a complete equipment and chemical reagent list. The precision of the methods is evaluated by a table showing analysis data on carefully mixed known developers.
