The determination of sulphur dioxide with rosaniline dyes

open access: yesThe Analyst, 1969
The compositions of commercial rosaniline hydrochloride (magenta) and pararosaniline hydrochloride samples have been re-investigated to improve the colorimetric determination of sulphur dioxide. The dyes, purified in small amounts by paper chromatography, each give a linear calibration up to 80 µg of sulphur dioxide, with the hydrochloric acid ...
