Method for preventing and inhibiting corrosion of power transmission line tower

The invention discloses a power transmission line tower corrosion prevention and inhibition method which specifically comprises the following steps: S1, selecting an iron wafer of a power transmission line tower, and polishing to obtain an iron wafer sample with a smooth and scratch-free surface; s2, dissolving the iron wafer sample which is polished to be smooth and free of scratches in 2-[(2, 4-dichlorophenyl) methyl]-1H-benzimidazole with the concentration of 0-1.1 mol by using hydrochloric acid with the concentration of 1 mol/L, and fully stirring until the iron wafer sample is completely dissolved; s3, drying the surface of the iron wafer sample, loading a working electrode, placing the working electrode, a counter electrode and a reference electrode, connecting a circuit for electrochemical testing, setting a voltage value and a scanning frequency, and storing test data. According to the corrosion prevention and inhibition method for the power transmission line tower, raw materials are cheap, a relative
