ION PAIR METHOD TO DETERMINE THE CTAB CONTENT IN GOLD NANORODS SAMPLES

In this work, we report a fast and accessible method for quantification of cetyltrimethylammonium bromide (CTAB) in solutions of gold nanorods (GNRs) by bromophenol blue (BPB) ion-paring formation and spectrophotometric detection. The ion-par method used to quantify CTAB exhibited adequate figures o...
