As shown in Figure Log Kow (19.1), pHpzc (10.5), pKa, and Molecular Weight (8.7) form a secondary importance cluster. This again indicates that hydrophobicity (Log Kow), ionization tendencies (pHpzc, pKa), and molecular size all play a role-albeit less crucial than surface area or initial concentration. Dose (g/L) (7.3), Temperature (5.6), pH (4.7), and S (4.6) follow, showing moderate influence. Notably, the solution pH remains relevant but at a smaller magnitude than in the Random Forest result.
