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

“…In the high concentration of electrolytes, it was observed that the color of the sample solution is close to the color of blank solution and the A620/A520 ratio was decreased. However, it is possible that electrolytes could change the surface of nanoparticles (Parham et al, 2015 andFarkhari et al, 2016). So that in the high concentration of electrolytes, interaction between TTA and nanoparticles decreased and thus aggregation decreased.…”

“…Therefore, there is a need to provide methods for the precise measurement of its very low amounts. There have been a variety of methods that have been applied to determine diazoles some of which Mercaptobenzothiazole (MBT) [4], Benzotiazole (BT) [5], Benzotriazole (BTA) [6] and also ultraviolet Spectrophotometry [7], Anodic chronopotentiometry [8], Amperometric titration [9], and High Performance Liquid Chromatography (HPLC) [10,11]. But the above mentioned methods have high, expensive and often timeconsuming costs.…”

In this study, the detection limit sensitivity to the level of μg L-1 was achieved. For this, by applying AuNPs signal fluctuations of high sensitivity was carefully monitored so that they become measureable with highest possible precision. The proposed method is capable of determining TTA over a range of 10-100 µgL-1 with a limit of detection 5 µg L-1. The relative standard deviation of the method was 3% and 1.5%. The obtained preliminary results from this study proved to be effectively successful in determination of TTA in water. A comparison between the proposed method and the previously published methods for TTA determination has also been made for the first time.

A resonance Rayleigh scattering (RRS) technique was utilized as a tool for isoelectric point monitoring and iron(III) cation determination. The spectral properties of some amphoteric molecules (proteins and a DNA sequence) were investigated using the RRS technique. When the pH values were kept at around their isoelectric points, especially high RRS signals could be obtained, which were much stronger than those at other pH values. By using the C30 DNA sequence as a probe, the iron(III) cation can be detected rapidly. After iron(III) was added to a C30 solution, a significantly decreased RRS signal was obtained. The sensing process can be finished within 10 min with a detection limit of 0.9 μM. Thus, a sensitive, selective, and label-free method was successfully developed for iron(III) detection.
