“…Starting from the good adsorption properties of silica and the importance of detecting toxic dyes in aqueous effluents, this work is aiming to prepare and characterize an electrochemical sensor based on glassy carbon modified with different types of silica for detection of Malachite Green, a toxic and carcinogenic triphenylmethane dye , widely used in dyeing enterprises as well as in food industry and aquaculture as antifungal, antimicrobial, and antiparasitic agent . Detection of Malachite Green can be accurately performed with HPLC coupled with mass spectrometry , flow injection analysis , spectrophotometry , surface enhanced Raman spectroscopy (SERS) , electrochemiluminescence , etc. However, all these methods require expensive and sophisticated apparatus and thus are not appropriate for applications in the field.…”

New silica‐modified glassy carbon electrodes prepared with three different sorts of ordered mesoporous silica (OMS) were characterized and tested for the electrochemical detection of Malachite Green (MG). The electrodes were prepared by drop casting using silica suspensions and, for stability sake, a Nafion coating was deposited on the electrode top by the same technique. Square wave anodic stripping voltammetry was used to investigate the effect of various experimental parameters (deposition time, solution pH, silica type and concentration) on the performance of the modified electrodes. The best electrode (GC/MCM‐41‐NH2/Nafion) with detection limit 0.36 μM, sensitivity 0.164±0.003 A/M; linear domain 1–6 μM was applied to detect MG in a commercial product commonly used as biocide in aquaria for ornamental fish.

“…However, these prohibited drugs are still frequently used in many places around the world, due to their low cost and effectiveness in the control of fish diseases [14,15,16]. Ultra-sensitive chromatographic methods, such as liquid chromatography-tandem mass spectrometry (LC-MS/MS) with a limit of detection equal to or below 1 ppb are required to analyze these zero-tolerance chemicals in fish and fish products [17]. SERS methods could be sensitive, easy-to-use, and affordable, serving as a good alternative to the more complicated and expensive chromatographic method.…”

Detection of Prohibited Fish Drugs Using Silver Nanowires as Substrate for Surface-Enhanced Raman Scattering

et al. 2016

Surface-enhanced Raman scattering or surface-enhanced Raman spectroscopy (SERS) is a promising detection technology, and has captured increasing attention. Silver nanowires were synthesized using a rapid polyol method and optimized through adjustment of the molar ratio of poly(vinyl pyrrolidone) and silver nitrate in a glycerol system. Ultraviolet-visible spectrometry, X-ray diffraction, and transmission electron microscopy were used to characterize the silver nanowires. The optimal silver nanowires were used as a SERS substrate to detect prohibited fish drugs, including malachite green, crystal violet, furazolidone, and chloramphenicol. The SERS spectra of crystal violet could be clearly identified at concentrations as low as 0.01 ng/mL. The minimum detectable concentration for malachite green was 0.05 ng/mL, and for both furazolidone and chloramphenicol were 0.1 μg/mL. The results showed that the as-prepared Ag nanowires SERS substrate exhibits high sensitivity and activity.

“…Indeed, MG has been extensively used in fisheries for many decades due to its low cost, ready availability, and high efficacy for the treatment or prevention of external fungal and parasitic infections in fish [2,3]. But later, it has been found to be toxic and tumor promoter [4,5,6,7,8,9].…”

Efficient Photocatalytic Degradation of Malachite Green in Seawater by the Hybrid of Zinc-Oxide Nanorods Grown on Three-Dimensional (3D) Reduced Graphene Oxide(RGO)/Ni Foam

et al. 2018

View full text Add to dashboard Cite

A hybrid of ZnO nanorods grown onto three-dimensional (3D) reduced graphene oxide (RGO)@Ni foam (ZnO/RGO@NF) is synthesized by a facile hydrothermal method. The as-prepared hybrid material is physically characterized by SEM, XRD, Raman, and X-ray photoelectron spectroscopy (XPS). When the as-prepared 3D hybrid is investigated as a photocatalyst, it demonstrates significant high photocatalytic activity for the degradation of methylene blue (MB), rhodamine (RhB), and mixed MB/RhB as organic dye pollutants. In addition, the practical application and the durability of the as-prepared catalyst to degradation of malachite green (MG) in seawater are firstly assessed in a continuous flow system. The catalyst shows a high degradation efficiency and stable photocatalytic activity for 5 h continuous operation, which should be a promising catalyst for the degradation of organic dyes in seawater.
