“…Cerium (III) solutions from penem pilot plant solutions containing up to 1.2 M Ce(III) were recycled in a two compartment Electro Syn Cell. Typical recycling conditions: Nation diaphragm with coated Ti-anode, applied current densities = 50-150 A/cm2; yield > 90%; processed amount: about 475 kg CAN [46,126,136,137]. The simultaneous determination of Ce(III) and Ce(IV) in the pilot plant solution and in solid CAN can be performed polarographically.…”

Typical dietary components such as vegetables, wheat flour, milk, chicken and drinking water samples have been analyzed for the quantification of essential trace elements like Zn and Cu and potentially toxic trace elements like Pb and Cd. The sensitivity, selectivity and cost effectiveness of Differential Pulse Anodic Stripping Voltammetric method at Hanging Mercury Drop Electrode has been evaluated and used for the analysis. A database covering the adequacy and safety of trace elements through common food articles was first contrived for the Islamabad region. This was followed by assessment of the mobility rate of the heavy metals in the soil, plant system for evaluation of the environmental impact. The method used was also validated using appropriate certified reference materials.

Metrological properties of voltammetric electrodes, in the situation where on their surface an electrochemical reaction of oxidizing/reduction takes place, were analyzed in this chapter. The properties of electrodes on which a reaction controlled by ion transport process takes place were taken into consideration. Also, it was analyzed how the electrode's shape and the voltage polarizing the electrode influence this electrode's metrological properties. The result of the analysis conducted is that in case of a reaction controlled by charge exchange process, such a voltammetric electrode functions like a converter type 0. Its metrological properties in the time domain are defined solely by sensitivity. However, if on the surface of the electrode there is a reaction controlled by ion transport process, the electrode will function like a converter type I. Its metrological properties in the time domain are defined by the sensitivity and time constant. Numeric simulations were conducted in order to determine the influence of the electrode's shape and the polarizing voltage on metrological properties of the electrode. The results show that both the sensitivity and the time constant of the electrode can be influenced by choice of an electrode's shape and the shape of the polarizing voltage.
