Carbon paste electrode(CPE)is widely used in the field of electrochemical testing,which is composed by carbon powder and adhe-sive in a certain proportion.It has the advantages of non-toxic and wide potential range.The carbon paste electrode has limitations in the de-tection and analysis in some cases.Therefore,chemical modifiers are added during the preparation of the carbon paste electrode to form a chem-ically modified carbon paste electrode(CMCPE).The chemically modified carbon paste electrode inherits the advantages of carbon paste elec-trode and has other functions.However,there are few reports on the application of carbon paste electrodes and chemically modified carbon paste electrodes.It is hoped that it can arouse the attention of researchers to the chemically modified carbon paste electrode and promote the develop-ment of the field of chemically modified electrode.
