摘要

Preventing and controlling agricultural non-point-source pollution, advancing the agricultural industry, and facilitating cation–π interaction to address cation instability and fertilizer loss are crucial for advancing agricultural sustainability. Due to the unique π-bond characteristics of GO (graphene oxide), it was selected as a cation carrier to improve fertilizer anti-loss capabilities and facilitate the effective release of nutrient ions. By adjusting the interface properties of GO, RGO (rippled graphene oxide) and CGO (crumpled graphene oxide) were successfully prepared, and their interactions with cations and the impact on sustained-release performance were studied. The selected optimal kinetic model provides a theoretical basis for material design. The results indicate that RGO-Zn1 (Zn2+/RGO = 16.7%) can not only effectively control agricultural non-point source pollution but also promote the cultivation of high-zinc rice. This study not only proposes an innovative solution for soil improvement and agricultural transformation and upgrading but also offers fundamental scientific insights into the cation-π interaction mechanism during transmembrane permeation.
