Procedure

The pH of the filtrate from A (contains about 0.20 mole sodium pyridine-2-thiol-N-oxide) was adjusted to 6.5 and a 20% zinc sulfate solution added until no free sodium 2-thiol-N-oxide was detected (via a ferric chloride test). The mixture was stirred 0.5 hours, filtered and washed with water. The "wet cake" was used for color determination using a Hunter Lab Color/Difference Meter D 25DZ, according to AATCC test method 110-1972. A portion was dried and analyzed via titration.
