Organoclay effectively sequesters the herbicide atrazine through irreversible chemical bonds. Optimal sequestration occurred with 100-200 g kg-1 surfactant, showing high adsorption and minimal release.

Area of Science:

  • Environmental Chemistry
  • Materials Science

Background:

  • Atrazine is a widely used herbicide that can contaminate water sources.
  • Organoclays are modified clays used for adsorbing contaminants.

Purpose of the Study:

  • To evaluate the sequestration efficiency of organoclays for aqueous atrazine.
  • To determine the optimal surfactant loading for atrazine adsorption.

Main Methods:

  • Preparation of organoclays using a specific triazine surfactant and Gonzales bentonite.
  • Adsorption experiments using 14C-labeled atrazine in aqueous solutions.
  • Washing experiments to assess the reversibility of atrazine sequestration.

Main Results:

  • Organoclays with 100-200 g kg-1 surfactant showed the highest atrazine sequestration efficiency.

  • Apparent soil organic carbon-water partitioning coefficient (KOC) values exceeded 5000 L kg-1.
  • Less than 12% of sequestered atrazine was released after four washing cycles, indicating strong binding.

    • Conclusions:

    • The organoclay demonstrated efficient and largely irreversible sequestration of atrazine.
    • Nucleophilic aromatic substitution likely plays a role in the strong binding of atrazine to the organoclay.
