采用高效液相色谱仪,建立了喹啉铜在稻田水、稻田土壤、水稻植株、稻秆、谷壳和糙米中残留量的检测方法.稻田水、水稻植株、稻秆、谷壳和糙米用乙腈和1 mol/L的盐酸提取,土壤用乙腈和2 mol/L的氢氧化钠提取.稻田水无需净化,其余样品用正己烷和乙腈净化后,采用带有紫外检测器的高效液相色谱仪测定,流动相为V(磷酸盐缓冲液):V(乙腈)=60:40,流速0.8 mL/min,紫外检测波长为250 nm.结果表明:在0.05～5 mg/L范围内,喹啉铜质量浓度与其相对应的色谱峰面积之间呈良好的线性关系,线性方程为)y =231.55x-15.064,决定系数(R2)为0.998 5,达极显著水平.在0.05 ～1 mg/kg添加水平下,稻田水、稻田土壤、水稻植株...

The residue analysis method of oxine-copper in paddy water, paddy soil, rice plants, paddy rice straw, rice husk, and coarse rice was development based on high performance liquid chromatography detection. Paddy water, rice plants, paddy rice straw, rice husk, and coarse rice were extracted with acetonitrile and hydrochloric acid （ 1 mol/L） ; paddy soil were extracted with acetonitrile and sodium hydroxide（2 mol/L）. Paddy water was ready for injection after filtration, while the rest sample extracts were cleaned up with hexane/acetonitrile, ...
