采用反相高效液相色谱法,以0.02mol/L硼砂为流动相,YNG C_(16)H_(37),为固定相,检测波长288nm,测定隐形眼镜保护药水中EDTA二钠和山梨酸钾的含量。简便快速,结果准确可靠。回收率100.26％(EDTA)、100.36％(山梨酸钾)。相对标准偏差0.85％(EDTA)、0.41％(山梨酸钾)。
Using reversed-phase high-performance liquid chromatography with 0.02mol / L borax as mobile phase and YNG C 16 H 37 as the stationary phase, the detection wavelength was 288nm. Disodium EDTA and potassium sorbate Content. Simple and quick, accurate and reliable results. The recovery rate was 100.26% (EDTA) and 100.36% (potassium sorbate). The relative standard deviation was 0.85% (EDTA), 0.41% (potassium sorbate).
