This CL system has been recently adapted to
HPLC for the simultaneous determination of NMCs (propoxur,
bendiocarb, carbaryl and promecarb) in fruits, achieving
detection limits ranging 3.9–36.7 ng L−1 for water samples and
0.5–4.7 g kg−1 for fruits [10]. It has been also found that some
carbamates were able to enhance the electrogenerated CL
intensity of Ru(bpy)32+ greatly at a multi-wall carbon nanotube
(MWNT)/Nafion composite film-modified electrode.
