acceptor type of chemodosimeter for cyanide in water. The water solubility of the probe 5 is due to the incorporation of two glycerol units on the starting prepared chemodosimeter. This sensory system is able to selectively distinguish cyanide among fluoride and many other anions at micromolar concentrations and instantly detect cyanide in water at ambient temperatures with a detection limit down to 1
一种简单的水溶性醛官能化色酮5被用作水中氰化物的双活化迈克尔受体型化学计量仪。探针5的水溶性是由于在开始制备的化学计量仪上引入了两个甘油单元。该传感系统能够在微摩尔浓度下选择性地区分氟化物和许多其他阴离子中的氰化物,并能在环境温度下以低至1.0 mM的检测限立即检测水中的氰化物。因此,将化学计量仪5用于饮用水样品(从饮用水开始)中氰化物阴离子的定量测定。
