It is shown that the very sensitive reaction between manganese and 4:4′‐tetramethyldiaminodiphenylmethane (‘methane base’) in the presence of periodate can be applied to the quantitative estimation of the element in the range 0.1–1 μg. The effect of possible interfering factors is studied and the method is shown to give satisfactory results for the determination of manganese in plant material and in the ammonium acetate ‘leachate’ of soils.
