研究了粒径为０．０４８－０．０５０ｍｍＦｅＯ４与Ｃｒ２Ｏ３在过氧化氢－柠檬酸水溶液中溶解特性。单一组分的Ｈ２Ｏ２的柠檬酸分别对Ｃｒ２Ｏ３和Ｆｅ３Ｏ４有较主的溶解量，而混合体系则大大降低了ＣｒＯ３和Ｆｅ３Ｏ４的学解量。

The studies on the dissolution characteristics of Fe3O4 and Cr2O3 whose particle dimension is 0.048￣0.050 mm in hydrogen peroxide /citric acid aqueous solution(Fe3O4 or Cr2O3/solution ratio:30 mg/50ml) have been performed.The hydrogen peroxide and citric acid in aqueous solution of single component can dissolve a small quantity of Cr2O3 and Fe3O4 respectively but the composite system of hydrogen peroxide and citric acid can only dissolve minute amounts of Cr2O3 and Fe3O4.The portion of the dissolved Fe3O4 in the composite system of hydrogen pe...
