Thesis Title: Optimization of the Process Parameters for the Photocatalytic Degradation of Tartrazine Using Sunlight Irradiation

Preliminary Draft of Methodology

Acknowledging the fact that any research involving experimental studies requires a well-planned

methodology, the researchers have formulated a simplified preliminary draft of methodology as

presented below. The intricate details of each process shall be discussed in the formal Chapter 3 –

Methodology.
