pH值、OH^(-)和S^(2-)离子对紫外可见分光光度法测定咪唑啉类缓蚀剂浓度的影响

Effects of pH,OH^(-)and S^(2-)on Determining Concentration of Corrosion Inhibitor with Imidazoline by UV-VIS Spectrophotometry

应用紫外可见分光光度法确定咪唑啉缓蚀剂残余浓度曲线。研究不同pH值的变化对吸光度影响,研究表明pH值在4~7范围变化对吸光度结果影响较小。

Residual concentration curve of imidazoline was established by UV-VIS spectrophotometry.Through studying influence of different pH on the absorbance,it was found the pH in the range of 4-7,OH-and S 2-had little influence on the absorbance results.
