Question

As a new engineer in a company XZ, your boss has assigned you a project that is related to the removal of pollutant A in pharmaceutical wastewater. To achieve the objective of the project, you had conducted the experiment in a batch mode. The initial concentration of the pollutant A was set at 2.5 mol/dm3. The remaining concentration of the pollutant was identified using a UV-Vis. The complete experimental data obtained is tabulated in Table 1.

Table 1

t (hr) 5 10 15 20 25

A (mol/dm3) 1.95 1.65 1.15 0.88 0.60
