Process Conditions of the Degradation of Rhodamine B by Cu_2O/Bi_2O_3 Photocatalytic

This paper used supported catalyst Cu2O/Bi2O3 to study the degradation of soluble dye rhodamine B,and surveyed the impact of degradation conditions on catalytic degradation process of Rhodamine B.The results show that it has better degradation effect,degradation of 5mg/L Rhodamine B solution nearly to 100% for 5 minutes,under the optimum conditions its pH is 3-5,the catalyst is 1g/L,and the amount of hydrogen peroxide is 1.0%(volume ratio).
