Determination of Furazolidone Residue in Shrimp by Capillary Electrophoresis with Amperometric Detection
Abstract:
A method for the determination of furazolidone residue in shrimp by high performance capillary electrophoresis with amperometric detection system was established.Several parameters affecting the determination were studied,including running buffer concentration,acidity,sampling time and separation voltage and organic additive.Under the following conditions:Na2B4O7-NaOH(Na2B4O7 30 mmol/L,pH=9.0 as buffer solution,CH3OH as organic additive,25 kV as running voltage,a linearity exists between peak height (Y) and mass concentration (c) in a range of 0.5~100 mg/L,the linear coefficient is 0.999 2,determination limit is 0.01 mg/L.
