Degradation of Orange II by heterogeneous photocatalytic reaction using montmorillonite KSF
Degradation of Orange II in montmorillonite KSF (KSF) suspensions under irradiation by a 250 W metal halide lamp (lambda a parts per thousand yen 365 nm) was investigated. The degradation kinetics of Orange II in KSF suspensions followed the Langmuir-Hinshelwood model. The effects of KSF concentration, solution pH, initial Orange II concentration, carboxylic salts were studied.
