Determination of carbamates in nature water based on the enhancement of electrochemiluminescent of Ru(bpy)(3)(2+) at the multi-wall carbon nanotube-modified electrode.
A multi-wall carbon nanotube (MWNT)/Nafion composite film-modified electrode was developed in this paper, and its chemical and electrochemiluminescent (ECL) behavior of tris(2,2'-bipyridyl)ruthenium (Ru(bpy)(3)(2+)) on this electrode has been investigated in detail. It has been also found that some carbamates were able to enhance the ECL intensity of Ru(bpy)(3)(2+) greatly at this modified electrode. Based on which, a sensitive and simple method for determination of pirimicarb, methomyl, aldicarb and carbofuran were developed, and the proposed method has been applied to determine the carbamates in the nature water.
