چکیده
|
In this work, a composite of polyethylene glycol (peg) modified mos2 (peg-mos2) was synthesized and used as the stationary phase of open-tubular capillary column via a chemical bonding strategy. the peg-mos2 exhibited a sphere-like architecture through characterization of scanning electronic microscopy. p-phenylenediboronic acid was introduced as a linker to combine the peg-mos2 with capillary column. a capillary electrochromatographic method was established for the determination of nine sulfonamides by using peg-mos2-coated capillary column. the intra-day, inter-day, and column-to-column relative standard deviations (rsds) of migration time and peak area were in the range of 0.80–4.38% and 1.61–9.22%, respectively. the limits of detection were in the range of 20.4–64.8 ng/ml. the recoveries in environmental water and milk were from 83.26 to 116.29% and 80.86 to 118.22%. this work is the first report that peg-mos2 material is utilized as stationary phase for capillary electrochromatography.
