Copper Determination

A new copper sensitive all solid-state ion-selective electrode was prepared using multiwalled carbon nanotubes-ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate) nanocomposite as an additional membrane component. The effect of nanocomposite content in the membrane on the electrode parameters was investigated. The study compares, among others, detection limits, sensitivity, and the linearity ranges of calibration curves. Content 6 wt.% was considered optimal for obtaining an electrode with a Nernstian response of 29.8 mV/decade. An electrode with an optimal nanocomposite content in the membrane showed a lower limit of detection, a wider linear range and pH range, as well as better selectivity and potential stability compared to the unmodified electrode. It was successfully applied for copper determination in real water samples.

Abstract Ion-selective electrodes have been applied to analysis of blood electrolytes with some success. However, currently available ion-selective electrode systems tend to be elaborate and expensive. We describe a clinical electrolyte analyzer in which inexpensive ion-selective electrodes are used. The electrodes are in the configuration of thin wires and are all solid in construction. They may be dipped directly into undiluted 250-µl samples of serum or plasma, are nondestructive of the sample, and may be used with an expanded-scale pH meter, although a more sensitive electrometer is preferred. The complete electrolyte analyzer consists of an electrode holder, into which the electrodes are plugged, and a solid-state digital electrometer that displays units of electrolyte concentration. A discussion of the thermodynamics essential to the construction of reversible electrodes is also presented, as well as the results of a clinical study in which it is shown that data from a flame photometer and the electrochemical analyzer compare favorably.
