Abstract
By utilizing a new indirect trick, an old and cheap compound, zincon (2-carboxy-2'-hydroxy-5'-sulfoformazylbenzene), was found to be a "novel" highly sensitive and selective chemosensor for cyanide in pure aqueous solutions, with a detection limit of 0.13 ppm and a color change that could be observed by the naked eye.
摘要
通过采用一种新的间接方法，发现一种古老且廉价的化合物锌试剂（2-羧基-2'-羟基-5'-磺基甲酰苯并三氮唑）在纯水溶液中是一种用于检测氰化物的“新型”高灵敏度和高选择性化学传感器，检测限为0.13 ppm，且颜色变化肉眼可见。
