Observe the morphological characteristics of the adsorbent by scanning electron microscope, study the adsorption of lead and chromium in groundwater by Fe-Mn-Ce-PA6, and investigate the metal oxide content, adsorbent dosage, initial ion concentration, pH, ion concentration, respectively And so on the impact on the removal rate. Carry out adsorption kinetics and adsorption isotherm experiments to explore its adsorption law and regeneration performance research.
