For purposes of studying pollution, it is essential to have available highly sensitive methods of analysis. Atomic spectroscopy is becoming an increasingly important tool for determining trace metals. One objective of the research was to investigate means of enhancing existing sensitivities for several elements using this and other analytical methods. A study of different solvent systems for the atomic absorption determination of cobalt revealed that acetone results in best sensitivity. Solvent extraction of several elements as dithizone or APDC chelates into acetone was successful. A new anodic stripping voltrammetric method was developed for stability studies of the poorly characterized APDC chelates. Over sixty elements were successfully measured by flame emission spectroscopy using the nitrous oxide-acetylene flame. Optimum instrumental and flame parameters and detection limits for each element were determined.
