Determination of cobalt in pharmaceutical products

Platinum and rhodium associated with the leaves of Nerium oleander L.; analytical method using voltammetry; assessment of air quality in the Palermo (Italy) area

“…The history, theoretical background and applications of voltammetry are given in references [46,47]. There are many reports on the application of voltammetry for the determination of Cu, Zn [48], Co [49] and Mo [50] in different matrices, but to the best of our knowledge, there are few reports on the application of the electrochemical method for the determination of ultra traces of Pt and Rh in complex such as environmental matrices [22,[51][52][53]. In this work, we use adsorptive stripping voltammetry (AdSV) and the differential pulsed voltammetry (DPV) to measure the concentrations of Rh and Pt in Nerium oleander leaves, respectively.…”

Development of a slurry introduction method for multi-element analysis of antibiotics by inductively coupled plasma atomic emission spectrometry using various types of spray chamber and nebulizer configurations

“…For single element analysis, the atomic absorption spectrometry is commonly applied [10][11][12][13], or atomic emission spectrometry [14,15] after digestion of the pharmaceutical sample. The development of plasma atomization techniques has recently enabled the multi-element analysis of various matrices, down to the g l −1 concentration level.…”

An overview of recent applications of inductively coupled plasma-mass spectrometry (ICP-MS) in determination of inorganic impurities in drugs and pharmaceuticals

“…Highly specific hollow cathode lamps are used for determination of each metal. Inductively coupled plasma-atomic emission spectrometry (ICP-AES) plays a significant role in the analysis of pharmaceuticals [15,16]. It is a multi elemental technique but suffers from complex spectral interferences and accuracy at ultra trace levels.…”
