Adsorption isotherm and kinetic analysis of molecularly imprinted polymer with two functional monomers for quantification of atrazine

The extensive use of atrazine as a pesticide in agricultural practices poses a significant risk to the environment and human health. Atrazine, when applied to plants, has the potential to migrate through the soil and contaminate groundwater sources. Consequently, there is an urgent need to explore a...

Abdul Halim, A. Kushairi, S.J. Che Lah, N.F. The extensive use of atrazine as a pesticide in agricultural practices poses a significant risk to the environment and human health.
