✦ Synopsis

Potentiometric stripping analysis (p.s.a.) methods for the measurement of manganese-(II) in natural waters are described; batch and flow approaches are discussed. The more versatile flow p.s.a. technique is suitable for concentrations in the range 2 nM-30 PM. Application of these techniques is illustrated by measurements in a variety of natural waters. Interferences arising from manganese-copper interactions in the mercury electrode can be suppressed by the addition of zinc or gallium depending on the concentration of the interfering copper. The relative merits of the batch and flow p.s.a. techniques are discussed.

## Abstract An internal standard method is proposed in the stripping analysis of natural waters. The method consists of the introduction into the sample solution of a reference element and subsequent calculation of the concentration of several elements by the increase in the analytical signal from
