Origins of Effective Charge of Multivalent Ions at a Membrane/Water Interface and Distribution of 2,3,4,5-Tetrachlorophenol in a Membrane Model System

Abstract

First and foremost of all I would like to thank my advisor Pavel Smejtek. With his inspiring humor and scientific comprehension he created a productive but at the same time relaxed working atmosphere. Our fruitful discussions helped me to get a better understanding about the "mysteries of physics" with which we were dealing. The experiments would not have been possible without the encouraging help from Shanru Wang. She had the patience to teach me the basic principles of "wet chemistry" and helped me to overcome many obstacles and frustrations. I am indebted to John Dash who supported my interest in electron microscopy and helped me to get the SEM micrograph of a liposome. I enjoyed working with Isolde Sieder and Robert Ward in our lab. Our discussions and late night sessions won't be forgotten! I want to thank the Physics Department here at Portland State for the obligingness I received in various matters and the unbureaucratical way administrative obstacles were overcome. I appreciate the help from Margie Fyfield during the final writeup of the thesis and all the discussions we had throughout the year. I am grateful for the financial support from the Oregon-Baden Wiirttemberg exchange program. I would like to thank all my friends, here and in Germany, who cheered me up during the busiest time of my research. My family had a major influence on my personal and educational development. Without their support I probably would not have been able to be here at Portland State and would have missed this extraordinary experience. Thank you!

Electrostatic Interactions at Membrane-water Interfaces and Distribution of 2, 4, 6-Trichlorophenol in a Membrane Model System

“…Similar behavior was found for 2,3,4,5-Tetrachlorophenol which was studied by Schmidt ( 1995) using the same experimental methods and for pentachlorophenol (Smejtek and Wang, 1993). The partition coefficients of these three different chlorophenols are shown in Table 6.…”
