| titleOfInvention | Method for detecting chloride ion content on surface of cold-rolled steel plate or steel strip |
| abstract | The invention provides a method for detecting chloride ion content on the surface of a cold-rolled steel plate or steel strip. The method includes placing a test sample plate in 2-10% diluted nitric acid solution, heating to 50-80 DEG C., adding isopropanol accounting 5-30% of the total column of the solution, soaking for 10-30 min, taking out the sample plate, washing with distilled water, heating the soaking solution on an electric sand table and evaporating to below 10 mL, cooling, transferring to a 25mL volumetric flask, adding 3-5mL nitric acid solution (1+1) and 2-4mL silver nitrate solution with the concentration of 0.1mol/L, diluting to 25mL, standing for 20-40min, detecting absorbance thereof at 450nm by an ultraviolet spectrophotometer, reading the chloride ion concentration in the sample according to the standard curve, and calculating the chloride ion content on the surface of the steel plate according to the formula (1). The method is simple, can maximally transfer chloride ions into the solution, has high detection accuracy, and can actually reflect the content of chloride ions on the surface of the cold-rolled steel plate or steel strip. |
