In addition, the results indicated that Fe⁰ was oxided to iron oxide or hydroxide after reacting with MC-LR, while Ni or Pd acted as the catalysis to prevent Fe⁰ corrosion and generating hydrogen via water reduction. Degradation of MC-LR by iron-based nanoparticles fitted well to the pseudo-first order kinetic model and the degradation was a diffusion-controlled reaction with low activation energies (8-21kJmol^-1). Finally, the degradation mechanisms of MC-LR using iron-based nanoparticles were proposed according to the LC-MS analysis. In nZVI case, when the MC-LR was quickly adsorbed on nanoparticles, electron transfer and H₂ generated from iron corrosion were generated and broke down the Adda composition of MC-LR. Based on corrosion in the Fe⁰-H₂O system, bimetallic Fe/Ni and Fe/Pd further utilized the abundant hydrogen radical decomposed from H₂ under the catalysis of Ni or Pd, and destroyed the Adda to form small molecules.]]> Sat 24 Mar 2018 07:09:43 AEDT ]]>
