Abstract
At room temperatures (approximately 25° C) dilute aqueous solutions of representative samples of methylene blue are stable below pH 9.5. Oxidation, or dealkylation, begins between pH 9.5 and 9.8 and increases in both rate and degree with increasing alkalinity. Below pH 11 the rate is slow and the total oxidation relatively limited. At pH 12, however, oxidation is rapid and is practically complete within a few days.This publication has 0 references indexed in Scilit:
