Method be referred to as this method.
The principle of this method degradation of dye is：
Inferior sulfate radical generates SO under the irradiation of sunlight or ultraviolet light3─Free radical and aqueous electron eaq ─, this two step
Continuous electronic transfer process is as follows：
SO3 2─+hv→·SO3 ─+eaq ─
·SO3 ─+H2O→SO4 2─+2H++eaq ─
The 1molSO it can be seen from reacting above3 2─2mol aqueous electrons e can be generatedaq ─, thus introduce SO3 2─It is anti-afterwards
Answer the aqueous electron e in systemaq ─It increases sharply, accelerates aqueous electron eaq ─The migration rate for moving to dye molecule surface, is conducive to
The progress of photo catalytic reduction reaction.
At the same time, SO3 ─With O2Reaction generates SO5 ─And SO4 ─, then SO4 ─It then reacts life with water
At OH, specific reaction process is as follows：
·SO3 ─+O2→·SO5 ─
·SO5 ─+SO3 2─→SO4 2─+·SO4 ─
·SO4 ─+H2O→SO4 2─+·OH+H+
It should be noted that above-mentioned OH, SO3 ─、·SO4 ─、·SO5 ─It is among the free radical of reaction generation
Body.
In conclusion above-mentioned reaction generates SO5 ─、·SO4 ─There is strong oxidizing property with OH free radicals etc., to dyestuff
Effect is photocatalysis oxidation reaction.In short, in the system simultaneously include photo catalytic reduction reaction and photocatalysis oxidation reaction, this
Play the role of to fast degradation dyestuff vital.
The advantages of this method：This method, can fast degradation using inferior sulfate radical under the irradiation of sunlight or ultraviolet light
