Nanoparticle Assisted Fabric Phase Sorptive Extraction for Azo Dye Determination in the Industrial Sewage.
Currently, one of the significant environmental problems is the presence of azo dye materials in water sources. In this study, for the first time, a fast and sensitive sample preparation approach using nanoparticle-assisted fabric phase sorptive extraction (NFPSE) followed by high-performance liquid chromatography was examined to remove some azo dyes such as methyl red and sunset yellow from aqueous solutions. Primarily, the significance of several parameters affecting NFPSE, such as fabric type, the kind of sorbent, the number of contacts with sol-gel and the time of contact, was investigated. In addition, experiments were performed to determine the effect of different adsorption parameters, such as sample volume, adsorption time, adsorbent value, desorption time, ionic strength and pH. It was found that the calibration curve was linear within two ranges of concentrations (0.05-0.1 and 0.5-15 ng/L for methyl red; 0.05-0.5 and 0.5-15 ng/L for sunset yellow) with correlation coefficients better than 0.9683. The limit of detection was 0.014 ng/L for methyl red and 0.015 ng/L for sunset yellow. Repeatability Relative Standard Deviation (RSD) with three replicated experiments was 1.5-10% for methyl red and 2.5-5.8% for sunset yellow. Relative recovery percentages of 88-96% for methyl red and 62-92% for sunset yellow were obtained in the samples. Moreover, the results have shown that acceptable accuracy, precision and linearity make the "fabric phase sorptive extraction" a proper method for the determination of dyes from industrial sewage samples.
期刊介绍:
The Journal of Chromatographic Science is devoted to the dissemination of information concerning all methods of chromatographic analysis. The standard manuscript is a description of recent original research that covers any or all phases of a specific separation problem, principle, or method. Manuscripts which have a high degree of novelty and fundamental significance to the field of separation science are particularly encouraged. It is expected the authors will clearly state in the Introduction how their method compares in some markedly new and improved way to previous published related methods. Analytical performance characteristics of new methods including sensitivity, tested limits of detection or quantification, accuracy, precision, and specificity should be provided. Manuscripts which describe a straightforward extension of a known analytical method or an application to a previously analyzed and/or uncomplicated sample matrix will not normally be reviewed favorably. Manuscripts in which mass spectrometry is the dominant analytical method and chromatography is of marked secondary importance may be declined.
