摘要
微波萃取反相高效液相色谱法对鳗鱼中磺胺类药物的含量进行测定。实验结果表明,采用微波萃取、分析时间短并可排除其它基质干扰,所用试剂少且污染小;与常规的萃取法进行比较,其精密度、重复性及方法的回收率均达到了分析要求。
After researching the test conditions, we introduce the microwave extraction and setup a system method viaHPLC to determine the sulfamethazine and the sulfadimethazine contained in eels. The method shows great selectivity, highsensitivity, good reproductivity. Also it shorten the length of the test and can obviate the interference comes from impuritiesas well. Secondly, two different extraction methods, regular extraction and microwave extraction are compared. The resultshows that with the help of microwave extraction, the preciseness and reproductivity are up to the standard and it is prettygood in recovery.
