Methods for determination of nonionic surfactants in surface water and wastewater have not been satisfactory since yet. Wickbold’s method is commonly used forsuch a purpose (1). This method consists of three time-consuming stages: (i) gas stri-pping separation of nonionic surfactants from water matrix, (ii) precipitation of ethox-
