drilling inserts suppliers Dioxin refers to the collectively chlorine-containing organic compounds which contain one or two oxygen-bond connecting with two benzene rings, the carcinogen with most toxic, very stable and difficult to break down, besides, the dioxin has reproductive, immunity and endocrine toxicity. The main active ingredients of de-dioxin catalyst are titanium dioxide, vanadium pentoxide, tungsten trioxide, cobalt oxide and other transition metal oxides, or a noble metal (platinum, gold, etc.). The researches on an efficient, economic catalyst with both functions of de-dioxin and denitration catalyst is very necessary.
