Abstract Despite prohibition in many countries, malachite green (MG) and crystal violet (CV) are illegally used aquaculture, endangering both human health the environment. Therefore, it is crucial to develop a method accurately detect MG CV. Surface-enhanced Raman spectroscopy (SERS) technology based on noble metal materials has attracted considerable attention for detecting food contaminations. However, of poor stability have very low affinity organic molecules. Herein, this study, covalent frameworks (COFs) modified with silver nanoparticles (Ag NPs) were as SERS substrates adsorption detection fungicides. COFs prepared by Schiff base reaction 1,3,5-tris (4-aminophenyl) benzene (TAPB) 2,5-dimethoxybenzene-1,4-dicarboxaldehyde (DMTA) had huge specific surface area could provide sufficient sites Ag NPs grown not only generated dense “hot spots” but also improved their stability. The results showed that COF@Ag exhibited high enhancement factor (1.4 × 10 6 ), reproducibility (RSD = 6.18%), good within 50 days 8.88%). Regression analyses ranges 0.0001–10.0 mg/L 0.0002–10.0 limits (LOD) standard solutions CV 3.8 −5 1.8 mg/L, respectively. Furthermore, fish samples, significant recoveries 90.83–107.91% 98.60–116.69% achieved. Hence, hoped work expand application COF trace analyses.

Triphenylmethane (TPM) fish drug residues and their metabolites exist in many aquiculture waters can cause significant harm to consumers. Rapid, accurate, simultaneous detection of foods is protecting the safety aquatic products. In study, a new type polydopamine coated polydimethylsiloxane (PDMS-PDA) stir bar was prepared for automatic sorptive extraction enrichment malachite green, leucomalachite crystal violet, leucocrystal violet which are common TPM drugs used aquaculture. The surface PDMS matrix first turned hydrophilic by plasma treatment enhance evenness stability PDA coating. Therefore, PDMS-PDA its capacity selectivity towards TPMs. These were due synergisitic adsorption capacities dyes. A hand-held stirring device installed with on-site extraction. After that, portable mass spectrometer directly detected eluted targets without chromatography separation. Under optimized conditions. four analytes' lower limit 0.16-0.38 μg·L-1 obtained. Within 35 minutes, device, combing spectrometer, rapid pretreatment real sample analysis analytes recovery 84.3-110%. All these prove that assay exhibited potential application prospects waters.
