Sodium phosphate dibasic is an inorganic compound with alkaline pH and hygroscopic in nature.12 Numerous dye leakage studies have been performed on MTA when used as a root-end filling material using different types of dyes such as methylene blue, fuchsin,
rhodamine B, silver nitrate, India ink, and Pelikan ink.13,14 In this study
rhodamine B dye was used for dye penetration.
Rhodamine B, a chemical dye, is banned internationally and also by the Lebanese Health Ministry for potentially causing cancer.
The dye
Rhodamine B has been used for staining oils in media in Petri dishes with the aim of determining microbial lipase activity [16].
reported that the hierarchical tetranitrocopper phthalocyanine (TNCuPc) hollow spheres exhibited, simultaneously, high adsorption capacity and an excellent visible-light-driven photocatalytic degradation performance for
Rhodamine B under visible light.
Fine Bakers, which runs a sweet shop on Crosland Road, Thornton Lodge, was fined PS2,500 by Kirklees Magistrates' Court in Huddersfield for making and selling Indian sweets containing the additive
rhodamine B. The bright pink chemical, which is banned from use in foods, glows under fluorescent light.
Rhodamine B is a xanthene dye whose optical properties depend of several factors, such as solvent, concentration and pH value [2].
Rhodamine B is used as the dye because of its fluorescence at the excitation wavelength of 514 nm.
LINGERING ODORS In the new study, conducted at Stanford's Hopkins Marine Station in Pacific Grove, Calif., Epel and Luckenbach exposed patches of gill tissue from California mussels to solutions of seawater containing standard amounts of alcohol and a fluorescent red dye called
rhodamine B. Some solutions also contained other chemicals from a list including half-a-dozen musks.
They incubated the tissue for 90 minutes in a solution containing musk compounds and the fluorescent dye
rhodamine B. The dye reflects efflux transporter activity; finding
rhodamine B in the tissue would indicate the transporters were failing.
Under the optimal conditions , the effect for photocatalytic degradation of
Rhodamine B solution was also studied, and the removal rate of
Rhodamine B (10-5mol/L) reached 97%.
