For two types of freshwater investigated, under the conditions given, adsorption of soluble organic yellow material to aluminum oxide was about 98% on the basis of OD at 270 m µ . Elution of yellow material could be realized up to recoveries of 66–80% using phosphate buffers at p H = 7. At phosphate concentrations of 0.008 m and 0.3 and p H = 7 several fractions of yellow material could be eluted.
