摘要
Rhodamine B can be degraded using Prussian blue as a photo-Fenton like reagent under lambda > 420 nm visible irradiation. Kinetic studies show ln(C (o)/C (t) ) is linearly proportional to the reaction time during the photo-degradation process; thus, the degradation reaction obeys a pseudo-first order kinetic law. It is very interesting that the presence of salinity such as 0.1 M KCl can speed up greatly the degradation rate: the time to achieve 90.0% degradation ratio is shortened from 120.0 to 40.0 min under comparable conditions, which is very useful in the treatment of wastewaters with high content of salinity.
