Development and validation of a confirmatory HPLC method for simultaneous determination of Sudan dyes in animal tissues and eggs.
J. Chromatogr. Sci. 48(1) , 63-7, (2010) A simple and sensitive high-performance liquid chromatography (HPLC) analytical method for the simultaneous determination of six Sudan dyes (Sudan Red G, Sudan I, Sudan II, Sudan III, Sudan Red 7B, Sudan IV) in animal tissues and eggs was developed. Samples w... |

Solubilization of two organic dyes by cationic ester-containing gemini surfactants.
J. Colloid. Interface Sci. 376(1) , 112-8, (2012) Solubilization of two different types of organic dyes, Quinizarin with an anthraquinone structure and Sudan I with an azo structure, has been studied in aqueous solutions of a series of cationic gemini surfactants and of a conventional monomeric cationic surf... |

Accelerated removal of Sudan dye by Shewanella oneidensis MR-1 in the presence of quinones and humic acids.
World J. Microbiol. Biotechnol. 29(9) , 1723-30, (2013) Although there have been many studies on bacterial removal of soluble azo dyes, much less information is available for biological treatment of water-insoluble azo dyes. The few bacterial species capable of removing Sudan dye generally require a long time to r... |

An ultrasensitive and selective fluorescence assay for Sudan I and III against the influence of Sudan II and IV.
Biosens. Bioelectron. 42 , 136-40, (2013) We report on an ultrasensitive and selective fluorescence assay for Sudan I and III against the influence of Sudan II and IV based on ligand exchange mechanism. Calcein as a fluorescence indicator and Sudan I-IV as model analytes were employed to investigate ... |

Evaluation of impact of exposure of Sudan azo dyes and their metabolites on human intestinal bacteria.
Anaerobe 18(4) , 445-53, (2012) Sudan azo dyes are banned for food usage in most countries, but they are illegally used to maintain or enhance the color of food products due to low cost, bright staining, and wide availability of the dyes. In this report, we examined the toxic effects of the... |
