| titleOfInvention | Composite electrode and preparation method thereof and method for detecting ammonia nitrogen |
| abstract | The invention relates to the field of electrochemical analysis, in particular to a composite electrode and a preparation method thereof, and a method for detecting ammonia nitrogen content in water. The composite electrode is made of Ag and Fe 2 O 3 、TiO 2 And (3) forming a nanotube array. The preparation method comprises the following steps: firstly, preparing a titanium dioxide nanotube array electrode by combining a secondary anodic oxidation method with subsequent calcination; loading ferric oxide on the titanium dioxide nanotube substrate by combining cyclic voltammetry with subsequent calcination; finally, Ag/Fe is obtained by using a pulse electrodeposition method 2 O 3 /TiO 2 And (3) a composite electrode. The detection method of the ammonia nitrogen content comprises the following steps: by adopting a cyclic voltammetry method and utilizing the composite electrode and the electrochemical workstation, the ammonia nitrogen in water can be detected quickly, accurately and highly sensitively, and the detection range is 7.9-100 multiplied by 10 ‑6 mol/L, and is not influenced by other interfering ions except potassium ions; the method has the advantages of good selectivity, low cost, convenient operation and strong practicability. |
