Pipette-tip solid-phase extraction using cetyltrimethylammonium bromide enhanced molybdenum disulfide nanosheets as an efficient adsorbent for the extraction of sulfonamides in environmental water samples
Surfactant cetyltrimethylammonium bromide enhanced molybdenum disulfide was used as an adsorbent in pipette-tip solid-phase extraction for the pretreatment of sulfonamides in environmental water samples. The factors affecting the extraction recoveries of the analytes, including the sample pH value, amount of sorbent, type and volume of eluent solution, and salt concentration were optimized. This pipette-tip solid-phase extraction method demonstrated good linearity (0.05-10.0 mu g/L) with a coefficient of determination of 0.9984-0.9996, limit of detection (0.2-0.4 ng/L) and limit of quantitation (0.5-1.0 ng/L), good analyte recoveries (76-91), and acceptable limit of quantitation (<10%) under the optimized conditions. These results indicated that the proposed method was a good tool for monitoring sulfonamides in environmental water samples. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 29823-18-5, you can contact me at any time and look forward to more communication.
