Abstract:

Exhaustive Rhodamine B oxidation by means of contact glow discharge plasma in aqueous solution has been investigated. The rate of degradation in different conditions such as pH、H₂O₂、Fe²⁺、n-butanol, and other factors affecting was studied. The results showed that, there are faster removal rate when the solution was in a relatively higher acidity; H₂O₂ presence can improve the efficiency rate.Fe²⁺can promote reaction. Radical scavenger, n-butanol, inhibits the Rhodamine B removal significantly. Some major intermediate products were detected by HPLC and GC-MS, respectively.
