The metal content of selected manganese nodules from the Pacific and Southern oceans was determined as follows: boiling of a suspension of 100 mg sample in 25 ml of 4 M hydrochloride acid; filtering the acid leachate through 0.2 ~m membrane filters pre-rinsed with 4 N HC1; diluting the filtrate to 100 ml with distilled water; analysing the metal concentrations by atomic absorption spectrometry with standard solutions prepared in 1 M hydrochloride acid.
