This paper studies on the dissolved iron of the extracted juice under different freshness of sugar cane. The results show that colour of the juice is linear dependence to the iron content.

At the upper temperatures, only austenite is present, the 0.77% carbon being dissolved in solid solution with the iron.

在较高温度时，只存在奥氏体，0.77%的碳溶解在铁里形成固溶体。

Dissolved oxygen in the molten cast iron is a very active element just like oxygen in the atmosphere.

So while the additional dissolved iron triggered an earlier-than-usual phytoplankton bloom, as the metal triggered growth in a greater number of phytoplankton cells, the bloom was only 15-20% larger than normal because the growth was limited by the amount of available nitrogen, another vital ingredient required for the organisms to develop.

Iron minerals take up dissolved nutrients and carry them to the seafloor, where they eventually become preserved in rock.

Like other iron minerals, green rust readily absorbs dissolved elements onto its surface, but green rust is not only particularly efficient at this in many cases, it can also react with toxic dissolved trace metals to make them insoluble, and as a result, renders them in nontoxic forms.
