Document Type and Number:
WIPO Patent Application WO/2021/208305
Kind Code:
A1
Abstract:
The present invention relates to the technical field of polluted water treatment and applications, and specifically disclosed is a method for removing prosulfuron in water by using a montmorillonite adsorbent, comprising the following steps: first adding montmorillonite into prosulfuron polluted water, then stirring or oscillating the water for a certain period of time, performing centrifugal filtration, and finally, separating prosulfuron-adsorbed montmorillonite from treated water so as to remove prosulfuron from the water. The method for removing prosulfuron in water by using the montmorillonite adsorbent of the present invention has the beneficial effects that prosulfuron in water can be effectively removed, the method also has the advantages such as stable removal effect, corrosion resistance, heat resistance, and notoxicity, and meanwhile, the montmorillonite used in the present invention is low in energy consumption, economical and environment-friendly, and has a wide application prospect.
