▎ 摘　　要

NOVELTY - Preparation of electrochemical in-situ induced polyaniline-loaded graphene-modified electrode involves adding distilled water, 0.5-1% concentrated sulfuric acid and 3-5 mL aniline solution to an electrochemical reactor including a three-electrode system containing a graphite rod working electrode, a platinum plate counter electrode and a silver/silver chloride reference electrode, stirring at high speed of 1000-1500 rpm for 5-10 minutes, such that aniline is uniformly dispersed in the solution, applying 0.5-1 V potential for 100-200 seconds using an electrochemical workstation, such that aniline is formed into polyaniline and nucleated on the graphite rod, then adding 0.03-0.05 g graphene, performing cyclic voltammetry scanning, and drying the modified electrode at 25-30 degrees C. USE - Preparation of electrochemical in-situ induced polyaniline-loaded graphene-modified electrode used in removal of cadmium (claimed) in industrial wastewater. ADVANTAGE - The method enables preparation of electrochemical in-situ induced polyaniline-loaded graphene-modified electrode which realizes rapid enrichment of degradable microorganisms, and efficient removal of heavy metal cadmium ions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for removal of cadmium ions, which involves adding a carbon source to a mixed liquid of municipal sewage and phosphate buffer solution, enriching and cultivating electroactive microbial film using chronoamperometry, forming electroactive microbial film with a thickness of 80-90 mu m, adding cadmium ion-containing solution to a reactor, sampling at different time points, centrifuging the sample, filtering the supernatant to remove impurities, analyzing the sample using an inductively coupled plasma emission spectrometer, and calculating the concentration of cadmium ions in to-be-tested water.
