Study on Light Oxidation of A New Type of Magnetic Electrodeless Discharge Lamp

The new type of electrodeless discharge lamp induced by high Frequency magnetic field including spectrum;transmission of different wavelength rays in solution;generation of hydroxyl radical;degradation of reactive brilliant red X-3B was investigated and compared with mercury lamp.The results showed that(1) intensity of rays of the lamp at 400nm is two times larger than mercury lamp and ultraviolet is absorbed easily in solution;(2) production of hydroxyl radical was corresponded with the absorption of photos of low wavelength in solution and the maximal oxidation distance of the lamp is 6cm in our experiment;(3) the degradation of reactive brilliant red X-3B follows pseudo-first order kinetics and efficiency of the lamp is better than mercury lamp.Synergistic effects in degradation of reactive brilliant red X-3B is existed in the processes combined the lamp and magnetic field.
