Notizen:
An adsorptive linear sweep stripping voltammetric method has been developed for the determination of nitrosamines at polymer modified gold electrodes. N-nitroso-N-butyl-N-propylamine has been quantified over a 10-10 M to 10-6 M concentration range at Nafion modified electrodes. CA coatings inhibited the determination of N-nitroso-N-butyl-N-propylamine, while small enhancements were observed at CAB modified electrodes. This improvement may be due to the anionic butyrate groups within the CAB polymer facilitating nitrosamine sorption. It is postulated, that the insulating effect of the polymer and the incorporation of anionic moieties compete to give either a net enhancement or depreciation of analytical sensitivity.
