Determination of cadmium in tobacco by solid surface fluorescence using nylon membranes coated with carbon nanotubes

► New methodology for cadmium traces determination in tobacco samples. ► Carbon nanotube have been used for improve the sensitivity of fluorescent detection. ► It is an important contribution at green chemistry. ► This methodology showing good reproducibility with low operation cost. ► It uses non-polluting solvents preserving the analyte and the environment.
