应用非水电位滴定法测定烷基磷酸酯钾盐中的单、双酯,无需分离.测定的变异系数分别为3.0%和5.3%(n=12).本法有效消除了非离子表面活性剂和无机磷酸盐的干扰.适用于化纤油剂的质量检验和上油槽中油剂浓度的测定.
Non-aqueous potentiometric titration of mono- and di-esters of potassium alkyl phosphates was determined without variation and the coefficients of variation were 3.0% and 5.3%, respectively (n = 12). This method effectively eliminates nonionic surfactants And inorganic phosphate interference.Applicable to the quality inspection of chemical fiber oil and oil tank oil concentration determination.
