Dissolved cobalt is removed from water by precipitating iron and manganese

What is it about?

Trace metals in lakes and the oceans can be trapped by being bound to or within iron or manganese as it precipitates to form solids that settle to the bottom sediment. This work looks at a method for determining how much cobalt metal is associated with each of the manganese or iron oxides - which can be tricky to determine as they tend to overlap in the sediment profile.
