| Abstract | ||
| This study aims to define the various factors that influence the adsorption-desorption of linuron on organo-bentonite for develop controlled release formulations. Ca+2-bentonite surfaces were activated for the adsorption of linuron by simple ion exchange reaction using hexadecyl tributyl phosphonium (HDTBP+) or trimethybenzyl ammonium (BTMA) salts. The results show that HDTBP is a very good adsorbent for linuron. Release studies show that 32 % of linuron was released after 96h followed by a steady state release up to 21 days. No further release was observed. These results suggest that HDTBP+-Bentonite is a promising porous material for controlling linuron release. The application of these materials may improve the herbicidal activity of linuron, reduces the frequency of application and protects the ground water. | ||
