摘　　要：通过α-Fe_2O_3单分散溶胶在酒石酸溶液中的絮凝情况研究α-Fe_2O_3肢体粒子在这种絮凝剂中的稳定和絮凝机理.实验发现,α-Fe_2O_3单分散溶胶在酒石酸水溶液中的絮凝-稳定性受溶液中电解质浓度及pH值的制约.其絮凝机理属于吸附絮凝.Coagulation and stabilization mechanism of monodispersed hematite sols in tartaric acid was studied by means of coagulation of hematite colloidal particles in the coagulation agent. It has been found that coagulation-stabilization of monodispersed hematite sols depends on the contentration of electrolyte and the pH of the medium in the aqueous solution. Coagulation mechanism belongs to adsorption coagulation.
