摘要：
Struvite or magnesium ammonium phosphate hexahydrate (H16MgNO10P) was synthesized in the presence of sodium alginate to determine the impact of extracellular polymeric substances (EPS) on struvite formation. Bulk crystallization of struvite at a 1.3:1:1 molar ratio of Mg:N:P, respectively, showed that in the presence of increasing sodium alginate concentration, struvite crystal habit changed from prismatic to plate-like twinned morphology. A possible mechanism of the adsorption of sodium alginate at [001]cc facets of struvite is proposed.
