摘要：Gaseous bubbles are made to rise in two respective measuring columns (30,20)for purified reference water and for the water to be examined, which columns aresupplied with descending currents and drained by respective ascending dischargecolumns (34,24) and overflows (36,26); the bubbles are measured with a konimeter on therising sections, and the difference in rising times in the two columns is calculated, in orderto determine the extent of the presence of surfactants.
