2-巯基苯并噻唑自组装膜电极同时测定米吐尔和对苯二酚

Mercaptobenzothiozol self-assembled monolayer modified electrode was fabricated successfully,and cylic voltammetry and scanning electronic microscopy were used to characterize the SAMs modified electrode.The electrochemical behaviors of emtol and P-benzenediol were studied on the SAMs in Britton-Robinson buffer solution.The results of the experiments indicate that metol and p-benzenediol can be catalyzed on the SAMs.They can not only be determined singleness but also be determined in mixture simultaneously and doesn't interfere with each other in a large range of concentration.This method has been used to determine metol and P-benzenediol in waste photographic imaging agent with satisfactory results.
