First and foremost, praise God the Almighty for His blessings and allow me to complete this Final Year Project successfully, even in this pandemic outbreak of COVID-19.
I want to express my deep and sincere gratitude to my supervisor, Assoc. Prof. Dr Shariff Che Ibrahim for allowing me to conduct final year project under him. His willingness to supervise my project and guide me since day one. Most of the time, he always gave motivation and additional ideas to improve my project, which helped me a lot. It is a great pleasure and opportunity to be working with him.
Next, I wish to thank all lecturers, especially in the School of Chemistry and Environment, Faculty of Applied Sciences for teaching and guiding me. I will never forget the valuable knowledge and experiences for the past three years and lecturers from other faculties. I am so thankful for that.
Special thanks to my classmates and batchmates for the advice given while completing this thesis. All the information is helpful to me, including the necessary things that should be made aware.
I am so grateful for my parents, Mr Razman bin Jamil and Mrs Radziah binti Ahmad, family and friends for their love, support and for inspiring me throughout this research project. That is kind enough to support, especially in finance, to lend me a hand, share information, and exchange valuable knowledge. Only God can repay their kindness towards me.
