Abstract: | This paper reports accurate use of silanized support based substrate for surface-enhanced Raman spectroscopy (SERS) determination of illegal additives chrysoidin and malachite green. Detection of these illegal additives is very meaningful and the developed method meets this objective in a simple, rapid and cost effective way. Detection limits for chrysoidin and malachite green in aqueous solutions reached 0.001 mg/L and 0.0001 mg/L respectively. Linear relationship between the Raman intensities and chrysoidin concentrations in range of 0.001-0.05 mg/L was found with regression coefficient (R) of 0.994. To investigate the practical application performance of the method, the substrate was applied to detect chrysoidin in Sprite at 0.01 mg/L and malachite green in fish pond water at 0.0001 mg/L. The SERS method could be an alternative approach for monitoring illegal additives and toxic harmful substances. |
