We would like to express our project thanks to my lecturer, Dr. Kanchana Watla-iad for her invaluable help and constant encouragement throughout the course
of this work. I am most grateful for her teaching and advice. We would not have achieved
this far and this work would not have been completed without all the support that We
have always received from her. However, there are still many people who give advice for this project. We would like to express thank you to TA in analytical chemistry 2 laboratory
