Abstract

In this work, the surface of the platinum disk electrode was modified with p–aminobenzoic acid by the method of oxidative electrografting (OEG) and the mechanism was proposed. The density of carboxyl groups immobilized in this way was estimated using differential pulse voltammetry. In addition, the effect of preliminary modification of the electrode surface by carboxylated carbon nanotubes (c–MWCNTs) on the density of carboxyl groups was studied. Modification allowed consequently improving the analytical characteristics of the working electrode. [ABSTRACT FROM AUTHOR]

Abstract

Theoretical study of the possibility of interaction of one of the common substances in nature, carbon dioxide, with modified functional carboxyl and amine groups of carbon nanotubes and boroncarbon nanotubes of BC5 type was carried out. The results of interaction were analyzed and a comparative analysis of the efficiency of sorption interaction of the nanosystem with the carbon dioxide molecule was carried out. Recommendations for the further use of the results as a basis for the creation of a highly sensitive sensor device of a new generation for the detection of microcollections of substances are given.
