近年来对铜的催化分析法作了不少研究,但多是在水溶液一相中进行催化反应的.本文提出的铜的催化退色反应,其反应物和催化剂分别处在两个不相混溶的液相中.反应在两相混匀时进行.因此可利用萃取方法来控制反应时间. 众所周知,对有色物质A,在催化剂作用下与物质B产生退色反应,当B大过量时,则反应过程中B的浓度改变可忽略,而A的浓度随反应时间t的减小可用比色法测出,且可表示为
In recent years, many studies have been done on the catalytic analysis of copper, but most of them are carried out in aqueous solution in one phase.The proposed catalytic fading reaction of copper, the reactants and catalysts are in two immiscible Of the liquid phase reaction is carried out when the two phases are mixed so that the extraction method can be used to control the reaction time.As we all know, for the colored material A, under the action of the catalyst and the material B fade reaction occurs, when B excessive, then the reaction The concentration of B in the course of change can be ignored, and the concentration of A with the reaction time t can be measured by colorimetric method, and can be expressed as
