Adsorption of phenthoate and acetochlor from water by clays and organoclays

TTA(C14)-montmorillonite > DTA(C12)-montmorillonite. Phenthoate is adsorbed to greater extent than acetochlor by each adsorbent, which may be due to the higher hydrophobicity of phenthoate, indicating considerable hydrophobic interaction between adsorbent/adsorbate systems.
