Groundwater treatment using a solid polymer electrolyte cell with mesh electrodes

This article reports the high performance of a solid polymer electrolyte cell, equipped with a Nafion® N117 membrane packed between a Nb/boron‐doped diamond (Nb/BDD) mesh anode and a Ti/RuO2 mesh cathode, to degrade the insecticide imidacloprid spiked at 1.2-59.2 mg L−1 into low conductivity groundw...
