Detection of low concentrations of malachite green and crystal violet in water.
I. Šafařík,M. Šafařı́ková +1 more
TL;DR: A simple procedure for the detection of low concentrations of malachite green and crystal violet in water is presented and their presence in eluates was detected spectrophotometrically.
Journal ArticleDOI
Uptake, tissue distribution, and metabolism of malachite green in the channel catfish (Ictalurus punctatus)
TL;DR: Malachite green was rapidly absorbed and concentrated in the tissues during waterborne exposure and the rate of accumulation was directly related to pH of the exposure water.
Journal ArticleDOI
Determination of malachite green and leucomalachite green residues in water using liquid chromatography with visible and fluorescence detection and confirmation by tandem mass spectrometry
TL;DR: The findings prove that N-demethylated products of MG and LMG, reported as potential carcinogens, may be formed in living fish organisms not only during enzymatic action but also during photo-oxidative degradation in water.
Journal ArticleDOI
Determination of malachite green in aquatic products based on magnetic molecularly imprinted polymers.
TL;DR: The as-prepared MMIPs are promising materials for MG analysis in aquatic products and exhibited higher selective binding capacity for MG than its structurally related compound.
Journal ArticleDOI
Rapid determination of malachite green in water and fish using a fluorescent probe based on CdTe quantum dots coated with molecularly imprinted polymer
TL;DR: A fluorescent probe based on CdTe quantum dots (QDs) coated with molecularly imprinted polymers (MIPs) was fabricated for the determination of malachite green (MG) by the strategy of fluorescence resonance energy transfer (FRET) as discussed by the authors.

Electrochemical pretreatment of carbon fibre microelectrodes for the determination of folic acid
TL;DR: In this article, an electrochemical pretreatment regime was optimized for the determination of folic acid at cylindrical carbon fiber microelectrodes, which gave rise to higher faradaic and capacitive currents, presumably due to the presence of new surface functionalities.

Biotransformation of gentian violet to leucogentian violet by human, rat, and chicken intestinal microflora.
J J McDonald,C E Cerniglia +1 more
TL;DR: Cellular suspensions of microflora isolated from human feces and from intestinal contents of rat and chicken transformed the triphenylmethane dye gentian violet under anaerobic conditions to leucogentian violet, identified by HPLC retention time in a reverse phase system, and by mass spectral comparison with authentic compound.
Journal ArticleDOI
Post-column reaction for simultaneous analysis of chromatic and leuco forms of malachite green and crystal violet by high-performance liquid chromatography with photometric detection
TL;DR: In this paper, the chromatic and leuco forms of malachite green and crystal violet were readily separated and detected by a sensitive and selective high-performance liquid chromatographic procedure.
