提出了高效液相色谱定性定量分析黄原酸盐与氨荒酸混合物组成的方法。混合物经碘氧化后生成对称和非对称化合物 ,用正己烷萃入有机相 ,在RP1 8柱上以甲醇 -水 (85∶1 5,V/V)为流动相 ,2 4 0nm处检测 ,其校准曲线的线性范围为 6 2× 1 0 - 5～ 2 0× 1 0 - 3mol/L ,7次测定RSD <2 %。 A method for the qualitative and quantitative analysis of the mixture of xanthogenate and carbamide by high performance liquid chromatography was proposed. After the mixture was oxidized by iodine, symmetrical and asymmetric compounds were generated. The organic phase was extracted with n-hexane and detected at 240 nm with methanol-water (85: 1 5, V / V) The calibration curve has a linear range of 6 2 × 10 -5 to 20 × 10 3 mol / L and 7 determinations of RSD <2%.
