SUMMARY
The hydrolytic efficacy of foam-making blends on the basis of cationic and nonionic surfactants and hydrogen peroxide was tested against the organophosphate Fenitrothion. The length of alkyl chains in both classes of surfactants and their mutual ratios are not parameters which significantly influenced the reactivity of blends. On the other hand, an increase in the hydrogen peroxide concentration induced a significant increase in the velocity of hydrolysis of Fenitrothion.

KEY WORDS
