摘要
研究了在自制硅胶薄板上邻苯二酚、间苯二酚、对苯二酚异构体的薄层色谱特性.展开剂为苯:乙醚:冰醋酸=7:2:1(V/V/V),R_f值分别为0.59,0.53,0.48.检测限分别为1.07×10^(-4),1.64×10^(-4),1.90×10^(-4)mol/L.其他常见酚不干扰测定.可应用于实际样品的测定,回收率为96%～104%.
The simultaneous determination of o-, m- , p- dihydroxybenzene isomers on silica gel plate by thin-layer chromatography were studied. The R, values are 0.59, 0.53 and 0.48 respectively using a developping agent of benzene: ether: glacial acetic acid = 7:2:1 ( V/ V/ V). The detection limits are 1.07 × 10-4 , 1.64 × 10-4 and 1.90× 10-4 mol/L respectively. The determination was not interfered by usual phenols. This method has been applied to the determination of the actual sample with a 96% - 104% recovery.
