Analytical Methods for Organic Cyano Groups

Methods for complete analysis and identification of the many surface-active agents available are very limited. Absorption spectrophotometry (ultraviolet and infrared) shows great promise as a means of identifying and characterizing these surface-active agents after some preliminary separation. Chromatographic procedures will probably become an ideal way to bring about separations and might well compete against present titration methods for quantitative results. 7567 Springer International Publishing AG.

In contrast, recent organic pollution is caused primarily by phosphorus-based anthropogenic eutrophication, which also induces heavy metal pollution. In the present review, causes of the recent organic pollution are briefly introduced, and our approaches, based on studies of environmental water biosensing methods as tools for estimating the degrees of the recent organic pollution, eutrophication, and heavy metal pollution, are introduced. In order to understand their involvement in these processes, researchers are using sophisticated air-quality simulation models. In most cases, these models require individual species information.


Consequently, considerable effort is currently being directed toward the development and validation of analytical methods for measuring the concentration of nonmethane organic species in various ambient environments. Analytical methods currently used to define ambient concentrations of hydrocarbons and their oxygenated derivatives (carbonyls and organic acids) are summarized. This review emphasizes strengths and weaknesses of the various analytical techniques and shows where new or improved methods are needed.
