Abstract Zn-doped NaA molecular sieves were prepared by hydrothermal method using zinc nitrate, sodium metaaluminate, silica sol, etc. as raw materials. The samples characterized XRD, SEM, FT-IR, etc., 300W xenon lamp the light source. Rhodamine B (RhB) was used target degradant for photocatalytic experiments its activity. results showed that ion doping increased number of active sites on sieve...

5(6)-carboxy-rhodamine 110 isomers were rapidly synthesized by condensation of 3-aminophenol and trimellitic anhydride using microwave irradiation as heating method. after esterification of the two isomers, separation and hydrolyzation provided target products,5-carboxy-rhodamine 110 and 6-carboxy-rhodamine 110, in high yields. the results shows microwave irradiation can effectively reduce the ...

This study focuses on the photocatalytic degradation of Rhodamine B (RhB) in heterogeneous and homogeneous photo-Fenton reactions. In system, iron(II) doped copper ferrite CuII(x)FeII(1-x)FeIII2O4 nanoparticles (NPs) prepared our previous work were employed as potential catalysts. The photodegradation RhB was carried out a quartz cuvette located diode array spectrometer. experimental conditions...
