Abstract The recovery of phosphorus from excess sludge by the crystallization of struvite has a good prospect. However, it may be influenced by some organic matter in excess sludge, especially by extracellular polymeric substances (EPS). To elucidate the effect mechanism of EPS, struvite crystallization from supersaturated solutions was investigated in the presence of sodium alginate (SA) presenting similar properties to EPS based on the characterization of Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analysis. The results indicated that the growth rate and crystal size of struvite crystals significantly decreased with an increase of the SA concentration in a range of 0mg/L to 250mg/L. This phenomenon was assigned to the adsorption of SA on the growth site of struvite. Moreover, the adsorption was attributed to the interaction between Mg2+, POH in struvite crystals and the groups of COOH, C=O, COC in SA, whereas NH4+ was not involved in the interaction.
