Abstract
⺠We prepared clay adsorbents via two-step method to remove nonionic alachlor and anionic imazaquin herbicides from water. ⺠Layered beidellite clay was treated with acid in hydrothermal process with common silane coupling agents. ⺠It was found that the selective modification of clay samples displayed higher adsorption capacity for herbicides compared with acid activated clay. ⺠Clay grafted with 3-chloro-propyl trimethoxysilane is an excellent adsorbent for both alachlor and imazaquin. ⺠Triethoxy (octyl) silane grafted clay is more efficient only for alachlor removal.
