Estimation of non-ionic, surface-active substances in aqueous solutions by means of the Controlled Growth Mercury Electrode

Satisfactory results were obtained in the determination of Triton X-100 in the range from 0.05 to 20 mg L−1 (R.S.D. = 6%, recovery = 94-103%, r = 0.999, DL = 0.15 mg L−1). Applicability of the method was presented using the water samples from Białka and Dunajec rivers, from which NS were removed by addition of fumed silica.
