Study on using red mud to control phosphorus release in sediment
赤泥在控制沉积物磷释放中的应用研究

Sintered red mud has adsorption capacity due to its high in Ca and Fe oxides.The effects of applied red mud on sediment phosphorus release was studied by Lab simulations.The variation of phosphorus forms in treated sediment samples was analyzed,the results showed that adding red mud can facilitate the Fe/Al-P in sediment translating to the Ca-P(Pearson correlation analysis,r=-0.892,P<0.01,n=9),it also increase the sediments pH value.The most appropriate proportion of red mud application is 5%,under this con...
