Resumo: | In this work, for the first time, a highly sensitive method based on dispersive liquid-liquid microextraction coupled with positive corona discharge ion mobility spectrometry as a fast and inexpensive technique has been evaluated for the direct determination of melamine. The effective parameters influencing the microextraction efficiency, such as pH, the properties of extraction and dispersion solvent were investigated. Under the optimum conditions, analytical parameters such as linearity, precision and limit of detection were evaluated. The calibration graph of melamine determination using the proposed method has two regions of linearity from 0.5 to 70 ng mL-1 and 70 to 1500 ng mL-1, the limit of detection and limit of quantification are 0.25 and 0.5 ng mL-1, respectively, and the relative standard deviation was less than 3% for all experiments. The proposed method was successfully applied for the determination of melamine in the milk, dairy products and egg yolk. |
