| 中文摘要 | 目的 建立水中甲萘威和莠去津含量的固相萃取-高效液相色谱测定方法.方法 水样用Oasis HLB固相萃取,甲醇洗脱,以甲醇-水(体积比为55:45)为流动相,流速为0.8 ml/min,柱温为35℃,检测波长为220 nm. Symmetry Shield RP18色谱柱(150 mm*3.9 mm,mum)分离,采用高效液相色谱测定法测定水中甲萘威和莠去津的含量.结果 甲萘威和莠去津浓度在0.05～10.0mg/L范围内,甲萘威的回归方程为:y=316 263x-3509,r=0.999 9;莠去津的回归方程为:y=140 151x-258 6,r=0.999 9.以3倍信噪比计算,甲萘威和莠去津的检出限分别为0.000 2,0.000 5 mg/L.该方法的平均回收率为89.6%～97.0%,RSD 为4.0%～6.7%.结论 该法灵敏度和准确度较高,重复性好,适用于同时测定水中甲萘威和莠去津的含量. |
| 英文摘要 | Objective To establish a SPE-HPLC method for the determination of carbaryl and atrazine in water. Methods Carbaryl and atrazine in water were extracted with Oasis HLB and were eluted with CH_3OH, CH_3OH-H_2O (55 :45) was applied as mobile phase, the flow rate was 0.8 ml/min, detection wavelength was 220 nm, column was Symmetry Shield RP18(150 mm* 3.9 mm, 5 mum), carbaryl and atrazine in water were determined by PDA detector. Results The linear range of the method was 0.05-10.0 mg/L (y=316 263x-350 9, r=0.999 9, for carbary; y=140 151x-258 6, r=0.999 9, for atrazine), The lowest detected concentration was 0.0002 mg/L for carbary and 0.000 5 mg/L for atrazine, respectively (S/N ≥ 3). The recovery rates were 89.6%-97.0%, and the relative standard deviation was 4.0%-6.7%. Conclusion The method was sensitive, accurate and repeatable, which was applicable to the determination of carbaryl and atrazine in water. |
