摘要: 文章建立一套养殖水体中呋喃西林的高效液相色谱检测方法,通过呋喃西林理化性质研究为提取方法提供参考。试验结果表明液液提取不适用于水体中呋喃西林的提取,利用固相萃取效果最佳,比较了几种固相萃取小柱萃取效果,发现MCX、HLB、C18对NFZ具有保留作用,MCX适合用于处理偏碱性样液,HLB处理效果受pH影响较小,C18与HLB相比效果稍差。以HLB小柱浓缩水体中呋喃西林方法,回收率在85%~95%之间,相对标准偏差小于10%,检测限达到0.25μg/L,可应用于各类型养殖水体中的呋喃西林残留测定。

Abstract: We develop a method for nitrofurazone residue determined in the aquaculture water by High Performance Liquid Chromatography (HPLC).The stability of nitrofurazone was analyzed for the assistance to screen the determination condition. The results show that liquid-liquid extraction wasn’t suitable for extracting the nitrofurazone in water, while the solid-phase extraction is acceptable. The efficiency of several solid-phase extraction cartridges was compared to optimize the extract condition. MCX, HLB, C18 cartridge are capable of retaining nitrofurazone, which MCX is suitable for alkaline extract, HLB efficiency is insensitive to pH value, and the C18 is less effective than HLB. The methods, recovery of 85% -95%, relative standard deviation of less than10%, detection limit of 0.25μg/L, can be applied to scrutinize the nitrofurazone residue in aquaculture water.
