Optimizations and docking simulation study for metolachlor adsorption from water onto MIL-101(Cr) metal�organic framework

Adsorption performance, multivariate interaction mechanism and sensitivity analysis for the removal of the herbicide metolachlor (MET) by MIL-101(Cr) metal organic framework (MOF) are investigated using experimental, optimization models and computational technique. The MOF adsorbent was hydrothermal...
