[Effect and mechanism of removal of trace p-chloronitrobenzene in aqueous solution by ZnOOH/O3].

Zinc hydroxide prepared in laboratory was used as catalyst in catalytic ozonation of trace p-chloronitrobenzene (pCNB) in water. The catalytic mechanism was deduced through the effect of radical inhibitor t-BuOH on the reaction. Furthermore, affecting factors of catalytic activity were investigated.
