Summary:本发明是精确测定碱性水溶液中非离子型表面活性剂浓度的方法。该方法包括：将表面活性剂萃取到有机溶剂中，分离溶剂，形成着色络合物，该络合物可以定量测定以给出表面活性剂的实际浓度。 The present invention is a process for precisely measuring the concentration of a nonionic surfactant in an aqueous alkaline solution. The process comprises extracting the surfactant into an organic solvent, separating the solvent and forming a colored complex that can be quantitatively measured to give the actual concentration of the surfactant.
