The extensive use of atrazine in agricultural production has caused increasingly serious environmental risk. It is significant to establish an efficient and environmentally friendly method for removing or treating atrazine pollution from the environment. Herein, the original atrazine-based molecularly imprinted nanocomposite membranes (AMINMs) were first proposed by developing a biomass-based hybrid membrane strategy based on two kinds of inorganic nanoparticles. Inspired from the as-designed nanocomposite-integrated system, integrating biomass activated carbon nanoparticles (BAC) and SiO₂ nanoparticles as the porous fillers into basal membranes to improve the various properties of the molecularly imprinted nanocomposite membranes, and the specific effects of SiO₂/BAC nanoparticles were systematically examined. Adsorption (adsorption isotherm and adsorption kinetics) and permselectivity experiments were used to test and valuate the selective separation performance of the AMINMs. The valuable experimental results proved that the as-prepared AMINMs not only exhibit ideal specific adsorption ability (5.857 mg/g), but also possess excellent permselectivity performance for atrazine (permselectivity factor β is 2.34). Due to its high specific recognition ability and permselectivity, AMINMs showed great potential in atrazine pollution treatment.

基于生物质活性炭/ SiO ₂的印迹膜选择性分离阿特拉津：协同积分系统。

r去津在农业生产中的广泛使用已引起越来越严重的环境风险。建立一种有效的，环境友好的方法以从环境中去除或处理阿特拉津污染具有重要意义。在本文中，首先通过开发基于两种无机纳米粒子的基于生物质的杂化膜策略，首次提出了基于azine去津的分子印迹纳米复合膜（AMINMs）。受设计的纳米复合材料集成系统的启发，将生物质活性炭纳米颗粒（BAC）和SiO ₂纳米颗粒作为多孔填料整合到基膜中，以改善分子印迹纳米复合膜的各种性能以及SiO ₂的特殊作用/ BAC纳米粒子被系统地检查。吸附（吸附等温线和吸附动力学）和渗透选择性实验用于测试和评估AMINM的选择性分离性能。有价值的实验结果证明，所制备的AMINMs不仅具有理想的比吸附能力（5.857 mg / g），而且还具有出色的对at去津的渗透选择性性能（渗透选择性因子β为2.34）。由于其高的特异性识别能力和选择性，AMINMs在r去津污染处理中显示出巨大的潜力。
