Magnetic field enhanced electrocoagulation using iron electrode in removing glyphosate from aqueous solution

The widespread use and high solubility nature of glyphosate posed a significant threat to water contamination. Glyphosate is a non-selective herbicide for weed control in various agricultural applications. Electrocoagulation method was thus proposed to coagulate this pollutant, and a magnetic treatm...
