ABSTRACT
Of the many electrical parameters that can be measured, only three need be considered here as of practical importance-potential, current, and conductivity-thus opening the way to three techniques that really have something to offer in the area of environmental analysis, where samples are always complex and determinants of interest usually are present at very low concentrations. Electrical charge, measured in the technique known as coulometry, does indeed have important analytical applications (especially in the Karl Fischer determination of water), but not often in the field of environmental analysis, and therefore will not be discussed further.
