摘 要:利用石油磺酸盐(PS)红外光谱1060cm-l处的特征吸收峰,测定其含量,相对误差不超过±5%,准确度优于两相滴定法。PS中单磺酸盐和双磺酸盐的相对含量与其图谱中1200cm-1和1060cm-1两处吸收峰的相对峰高比的变化有关。测定的相对误差不超过±7%.The content of Petroleum Sufonate (PS) could be determined by means of its characteristic peak of 1060 cm -1 in infra-red spectra. It was demonstrated that the technique,with a relative error within ±5%, is of higher accuracy in detecting the PS content than the Epton method. The relative contents of mono sulfonate and di sulfonate were found to be related to the relative peak height ratio in 1200 cm -1 and 1060 cm -1 ,and in terms of the peak height ratio the content of mono sulfonate and di sulfonate was able to be determined within a relative error of ±7%.
