It has been known for a long time that molybdate and tungstate may be bound to Fe and Al oxides in soils and sediments, and that this process may determine the dissolution of Mo and W. However, very few studies have been made to quantify this process.
Ito ay may haba na- kilala na molybdate at tungstate maaaring may kaugnayan sa Fe at Al oxides sa soils at sediments, at na ang prosesong ito ay maaaring matukoy ang paglusaw ng Mo at W. Gayunpaman, napakakaunting mga pag-aaral ang nagawa sa tumyak ng dami ng prosesong ito.
