摘要：

The photodegradation of solutions of piroctone olamine in the absence and presence of anionic surfactants was studied. The photodegradation appeared to follow first order kinetics and was found to be pH dependent. The degradation rate constant was calculated to be 4.80.10(-3), 6.15.10(-3) et 4.35.10(-3) min(-1), respectively, for the diluted aqueous solution at pH 7.00, for the aqueous solution with anionic surfactants at pH 7.20 and for the aqueous solution with anionic surfactants at pH 3.96.
