Detection of trace metal in distilled alcoholic drinks
چکیده انگلیسی

The presence of trace metal cadmium assay was investigated with a copper immobilized on a graphite carbon electrode (GPC), the modified property of which was determined with handheld voltammetric systems. Following the determination of the analytical stripping conditions of 0.45 V amplitude, 30 Hz frequency, −1.4 V initial potential, and 4.0 mV increment potential, only a 60-s experimental accumulation time was used. Using these conditions, the analytical detection limit approached the nano range. At this condition, the analytical application was performed on distilled alcoholic drinks for food manufacturing systems. This developed technique is faster and less costly than the common voltammetric and spectrophotometric methods.


► Cadmium detection was performed with a copper immobilized on a graphite carbon electrode.
► Analytical detection time only a 60 s.
► Detection limit approached the nano range.
► Application was performed on distilled alcoholic drinks directly.
► Developed technique is faster and less costly than the common methods.
