Résumé / Abstract

In this article, ultraviolet absorption spectra (UV) without probe were used to determine the first and second critical micelle concentration (CMC) of cetyltrimethylammonium bromide (CTAB), and the transformation of congeries at the CMC were detected by 1H NMR spectra and dynamic light scattering, which just tested and verified the feasibility of using UV spectra without probe to determine the second CMC of the aqueous solution of CTAB. Furthermore, UV spectral method was also used to investigate the CTAB/KBr system, and it was confirmed that the formation of CTAB wormlike micelle could be induced by the aqueous solution of KBr.
