- The correlation coefficient value in bold indicated the highest correlation value and the most predominant order of the reaction
- R2 = Correlation coefficient, T1/2 = reaction half-life, K = rate constant in different units (first and pseudo-first order in min−1 and second and pseudo-second order in mg/L−1 min−1), qe = equilibrium concentration
