Degradation of rhodamine B with manganese dioxide nanorods [PDF]

Journal of Water and Health, 2018
Abstract This is an investigation on oxidative degradation of rhodamine B (RhB) by manganese dioxide (MnO2) nanorods synthesized by redox co-precipitation method. Field emission scanning electron microscopy of MnO2 nanorods at an electron voltage of 10 kV revealed a rod-like morphology for the synthesized nanoparticles. Fourier transform

Synthesis of a Toolbox of Clickable Rhodamine B Derivatives

, 2015
An efficient method for the large-scale preparation of rhodamine B clickable derivatives has been developed. Starting from inexpensive rhodamine B as the starting material it was possible to functionalize the carboxylic functionality of rhodamine B with ...

The photolysis of rhodamine B in solution [PDF]

Australian Journal of Chemistry, 1974
In the flash photolysis of aqueous alcoholic solutions of rhodamine B, the semiquinone radical of the dye is formed by absorption of light at wavelengths shorter than 300 nm. It is proposed that impurities in the alcohol sensitize the radical formation.

The effect of Rhodamine B on the cerebellum and brainstem tissue of Rattus norvegicus

Journal of Public Health Research, 2020
Background: Rhodamine B is a component of xenobiotic substance metabolized by cytochrome P450 in the body to produce free radicals, which affects the activity of Superoxidase Dismutase (SOD), thereby, leading to oxidative stress, injury, increase in cell

Readily accessible rhodamine B-based photoresponsive material

, 2013
A photochromic rhodamine B-based material containing Cd(II) as bridge was facilely prepared. The 4-methoxylsalicylaldehyde rhodamine B hydrazone Cd(II) complex displayed unusual ring-open response upon 365 nm UV irradiation, exhibiting long photochromic ...

Precipitation of Insulin with Rhodamine-B

Experimental Biology and Medicine, 1939
A few years ago one of the authors in unpublished results showed that rhodamine-B would precipitate pepsin from solution. Since the well known proteolytic ferment precipitating agent, safranine, also precipitates insulin,1 it was decided to determine if rhodamine-B would precipitate insulin and if so, whether the dye could be removed without ...
