摘要
为检测水果中单甲脒的残留，建立了水果中分析单甲脒残留量的特异性的高效液相色谱方法。采用盐酸作提取液，ＯＤＳ－Ｃ１８色谱柱，甲醇：醋酸铵溶液＝７５：２５流动相、紫外检测器２５４ｎｍ波长的仪器分析条件。该方法的最小检出量为２ｎｇ，方法的最低检测浓度为０．０２５ｍｇ／ｋｇ，方法平均回收率为７７．１４％～８９．１７％，适合单甲脒农药残留的分析。
A HPLC method for determination of monoamitraz residue in fruit was developed, based on: extraction(hydrochloric acid); methyl alcohol:sodium acetate anhydrous solution(75:25)as mobile phase; and deternination by HPLC on C18 column with ultraviolet 254nm detector. The detection limit was 2 ng and concentration limit was 0.025 mg/kg. The average recovery was 77.14%～89.17%. It is concluded that this HPLC method is suitable for analysis of monoamitraz residue in fruit.Author's address Zhang Ying, Institute of Food Safety Control and Inspection, Ministry of Public Health, Beijing 100021, PRC
