Sensitivity and detectability for manganese(II) determination in solution by kinetic methods of analysis.
The use of nitrilotriacetic acid to enhance the catalytic effect of manganese ions on the oxidation of Malachite Green cations is reported. This effect permits a noticeable increase in sensitivity for the determination of micro and submicro amounts of manganese ions in aqueous solution. The detectability, however, is not so dramatically altered. Comparison is made with other kinetic methods for the determination of manganese in solution.
