Hierarchical zeolites as adsorbents for mesosulfuron-methyl removal in aqueous phase
Résumé
Desilication and soft acid leaching lead to hierarchical zeolites with low debris.•Hierarchical zeolites are promising adsorbents for bulky pesticides in water.•Mesosulfuron-methyl (MM) is chemisorbed on zeolite Brønsted acid sites.•The zeolite mesoporosity enhances significantly MM diffusion behavior and capacity.•MM abatement rate is up to 80% in water for hierarchical large pore H-MOR zeolite.
