“…The wide range of hydrophobicity, ionic characterization, and steric hindrance has been used for chromatography in a variety of applications, such as bioactive compounds [86][87][88][89][90][91], natural products, foods, drugs, and fine chemicals [92][93][94], including polychlorinated biphenyls, alkylphenols, and parabens, PAH, and phthalate [95,96]. An interesting approach was proposed for applications in drug delivery using drug ILs [97].…”
