Rhodamine B is widely used in the dyeing of paints, acrylic and other fabrics as well biological products. It highly toxic to organisms when directly discharged into water. To this end, paper, degradation water by ultrasound-assisted TiO2 photocatalysis was investigated. The effects various factors, such amount catalyst, speed mechanical stirring, frequency ultrasonic vibration, output power, i...

Rhodamine B is a synthetic dye that usually used in the textile and paper industries. According to Permenkes No.239/Menkes/Per/V/85 regarding certain dyes, it states rhodamine dangerous substance. prohibited for use as food additive because has chelating compounds chlorine which can cause cancer humans. Based on above problems, review of articles was carried out by collecting journal literature...

N-(rhodamine B)-deoxylactam-5-amino-1-pentanol (dRB-APOH) was designed and prepared as the chromo-fluorogenic sensor for detection of a nerve agent simulant via analyte triggered tandem phosphorylation and opening of the intramolecular deoxylactam. The successful detection of diethyl chlorophosphate suggests the utility of rhodamine-deoxylactams as the chromo-fluorogenic signal reporting platfo...

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 ...
