Soil increased ability to sequester and retain carbon<\/strong> is known to be due, in some cases, to the presence of iron oxide<\/strong> minerals. However, the methods used by these minerals to capture the element have been ignored until now. Today, a study<\/a> by Northwestern University<\/strong> in Evanston, Illinois, published in the journal Environmental Science & Technology, reveals the details.<\/p>\n The study focused in particular on ferrihydrite<\/a>, a mineral that, the authors observed<\/a>, uses different chemical strategies to capture and trap the element.<\/p>\n
