摘要：

A coagulation model is postulated in which phosphate bridges to primary goethite particles and causes increased aggregate order, phosphate burial, and oscillatory uptake kinetics. This hypothesis is supported by electron diffraction patterns of single aggregates, decreases in exchangeable phosphate, phosphate-induced reduction in BET surface area, and long-term kinetic results showing slow release of phosphate.
