WebThe empirical solvent-sorbent interaction term for anionic PCP (αi) was inversely correlated with fHphilic (r2 = 0.82), which is consistent with methanol-induced increases in anion exchange. For neutral PCP, the empirical term (αn) was positively correlated with fHphobic (r2 = 0.84), supporting methanol-induced increases in solution and sorbent hydrophobicity. WebSolvent. Methanol.
