Abstract
The Equilibrium Phosphorus Concentration (EPC0) of Hohhot dust (HD) of Inner mongolia was measured to examine whether the HD acted as sources or sinks of soluble reactive phosphorus (SRP) to the Yellow River water column. The modified Langmuir isotherm equation was modified to describe phosphorus (P) adsorption on the HD in Yellow River water. The EPC0 was higher than P concentration in the overlying water, which indicates that the HD acted as sources of phosphate. In addition, solid concentration (Cs) effect existed obviously in P adsorption experiment and the hysteresis got bigger as Cs increased.
