The invention discloses multifunctional nickel complexes based on organic ligands, a method for synthesizing a carbon paste electrode and an application of the carbon paste electrode; the complexes have the following molecular formulas: [Ni(L)(H2O)4].(2,5-TPD) and [Ni2(L)2(1,3-BDC)2(H2O)4].5H2O; a complex graphite powder is ground by an agate mortar and then is dispersed into liquid paraffin, andthe mixture is ground by the agate mortar and is packaged into a quartz glass tube; one end of a carbon paste is wiped flatly with sulfuric acid paper, the other end of the carbon paste is connected with a copper bar connected with 6-11 copper wires, and the complex carbon paste electrode is obtained. The synthesis method is simple, and three kinds of pollutants comprising hydrogen peroxide, nitrite and chloramphenicol can be effectively monitored. Meanwhile, the carbon paste working electrode can be simply and quickly updated and has good stability. The research and development of the workingelectrode is of great sig
