Seven binary and three multi-component mixtures of non-ionic surfactants and a mixture of ethylene glycol and PEG 400 were investigated using tensammetry with "normal" recording and one binary mixture by using "reverse" recording. Within the initial section of the I-shaped calibration graph, the inv

Three alternative procedures for the determination of non-ionic surfactants (NS) in surface water have been developed. The simplest one consists of the filtration of water samples, the extraction of NS with ethyl acetate, the evaporation of the solvent and the determination of NS using an indirect

Chloroform, formaldehyde and ions of copperi and mercury(II) were tested as preservatives of water samples for determination of non-ionic surfactants (NS). River water (Warta River, Poznan) was used as hydrobiological background. Mainly the concentration of "native" NS from river water was measured,
