【Abstract】 The fundamental principles and relative characteristics of various determination methods of chlorine in reforming catalysts were introduced. The effect of p H and interferential ions on experimental results was investigated. The precisions and standard recovery rates of 3 kinds of methods were tested. The results indicated that the methods of potentiometric titration,ion chromatography and ion selective electrode have high accuracy and good repeatability.更多还原
