The main objective of this research was to develop a new approach for HAA analysis that was accurate, reproducible, sufficiently sensitive, and relatively safe and simple to perform. This method involved the use a CE ion analyzer for separation and detection of HAAs. Preliminary results from our laboratory using distilled and deionized water spiked with HAAs indicated that this approach was capable of separating and detecting all nine chlorinated and brominated HAAs. The method detection limit (MDL) for monochloroacetic acid measured in our laboratory was 32 ppb using a bubble cell without any sample pretreatment (i.e. direct aqueous sample injection). Given this unacceptably high MDL, more work was needed to fully develop and test the CE-based method especially with regard to improving method sensitivity.

The purpose of this monograph is to provide a summary for those who are active in the field of phthalocyanine research. This volume allows the reader to quickly-and at a reasonable cost-determine what is being accomplished so that he may plan his own research programs. It covers such topics as synthesis, reactions, inks, energy systems, coatings, toners, and electrophotographic plates and developers, just to name a few. Packed with over 40 structural drawings of phthalocyanine molecules, this one-of-a-kind reference provides the necessary description and visualization to stimulate further research. This work is an indispensable resource for researchers and practitioners, both novice and experienced, in the field of phthalocyanine science and technology.
