“…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.

“…The current analytical methods used to detect MG include high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS), [7] molecularly imprinted polymers (MIPs), [8,9] surface-enhanced Raman spectroscopy (SERS) [10,11] and electrochemiluminescence. [1,12,13] Among these sensing techniques, electrochemical analysis has been widely applied for the practical detection of MG because of its low cost, simple instrumentation, rapid response and high sensitivity. [14][15][16][17] Unfortunately, traditional electrodes, such as glassy carbon electro-des (GCEs), suffer a large overpotential and tend to be poisoned by the products generated during the electrochemical process.…”

The recycling of environmental wastes to produce value‐added materials is an attractive prospect for both economic and social development. Herein, we use natural crab shell as the templates to synthesize ordered mesoporous carbon nanofiber arrays (OMCNs) based on a combined hard‐templating and surfactant self‐assembly approach. The Brunauer‐Emmett‐Teller surface area of the OMCNs is calculated to be 1200 m2 g−1, which is accompanied by good conductivity and a mesoporous structure. The as‐prepared OMCNs exhibit a remarkable electrochemical performance for the detection of malachite green (MG). Differential pulse voltammetry (DPV) reveals that the MG sensor has a wide linear range from 0.1 μM to 22.1 μM with a low detection limit of 0.05 μM. The MG sensor also shows a good stability and excellent anti‐interference, which are investigated by cyclic voltammetry. Furthermore, such an electrochemical sensor is successfully applied for the determination of MG in fishery water samples.

“…There are two different applications for MG: it is widely used as fungicide, parasiticide and antiseptic in aquaculture and fisheries. Moreover, it is used as a synthetic dye in various industries, such as paper, leather, textile, food and cosmetic industries, and is continuously entering the ecosystem from these industries . However, many reports have shown that MG is teratogenic, carcinogenic and mutagenic for both humans and animals .…”

“…As a result, monitoring fish and environmental samples to detect MG has become very important in recent decades. Thus far, several methods have been used to determine MG such as spectrophotometry after solid‐phase extraction or solid‐phase microextraction, spectrophotometry after cloud point extraction, high‐performance liquid chromatography (HPLC), electrochemistry and fluorescent probe . These methods have disadvantages such as being time consuming and laborious, as well as requiring sophisticated instruments.…”

BACKGROUND Malachite green is used in aquaculture and fisheries as a fungicide and antiseptic and it is also used in industry as a dye. However, malachite green is carcinogenic and highly toxic for humans and animals. In this study, a spectrophotometric method was developed to detect malachite green. The method was based on the surface plasmon resonance property of gold nanoparticles and interaction between malachite green and gold nanoparticles. RESULTS Malachite green–gold nanoparticles were rapidly aggregated in the acidic medium; as a result, a color change from red to blue was observed, which was easily detectable by the naked eye. The absorption ratio (A623/A520) of the gold nanoparticles in an optimized system exhibited a linear correlation with malachite green concentration. The method detection limit and linear range were 3 and 50–350 ng mL−1, respectively. The method was applied successfully to detect malachite green in different samples. CONCLUSION The method was simple and rapid to detect malachite green. The most important advantages of the method are the possibility of malachite green determination with very good accuracy and sensitivity using a simple UV–visible spectrometer without any expensive or sophisticated instrumentation and also the versatility of real samples. © 2018 Society of Chemical Industry
