Anodic Stripping Voltammetry (ASV) is an important electrochemical measurement technology that is highly sensitive, easy to use, and has recently been extended to measure a wide range of aqueous ions and organic materials. The instrumental assay of aqueous ions has almost entirely replaced other methods. Techniques such as UV/visible spectroscopy, ion chromatography, and anodic stripping voltammetry (ASV), in particular, have all played a part in this change.
ASV is not just a technique for ions, however. It is also now also being applied increasingly to monitoring molecular species, especially organic chemical pollutants in water.
This group of related patents stems from a major long-term research programme at DERA Porton Down laboratories. Commercial companies supplying instrumentation to the scientific world, manufacturers of pollution monitoring equipment and companies supplying the water industry or the food industry will find this technology particularly interesting.
ASV is increasingly used commercially because it uses only simple small scale equipment, yet is capable of yielding analysis of contaminants at the level of 1 part per billion (1:109) or even 1 part per trillion (1:1012).
ASV avoids the main problems of mercury drop polarography, from which it was originally derived. It does not need a supply of liquid mercury to operate, and the mercury film electrode used in ASV releases essentially no mercury into the environment and is automatically regenerated during use. ASV is increasingly being incorporated into continuous flow or quasi-continuous flow analysers. Unlike many rival techniques ASV is suitable for portable use, e.g. in pollution monitoring. Originally ASV technology was only appropriate for the assay of heavy metal ions. However, in recent years the capabilities of the mercury film electrode have been extended to other ions - including anions and a surprisingly large range of the more reactive organic chemicals of interest, including organochlorines and DDT.
ASV methods have been developed for many important naturally-occurring organic compounds from simple aldehydes and quinones to complex molecules like some vitamins.我找的,目前还没有听说谁在用,问问上等兵
