A colorimetric method which can be used to determine concentrations of cobalt as low as mg/L in natural and waste water samples is developed. This method involves the complexation of cobalt with 1-nitrosonaphthol-3,6, disulfonic acid disodium salt at the pH ofand the measurement of the absorbance of the colored complex at nm.

The inner complex salt formed with 1-nitrosonaphthol is insoluble in water so the sodium salt of l-nitrosonaphthol-3,6-disulphonic acid commonly called nitroso-R-salt (N RS) was used instead.
