Carbon dioxide from the atmosphere can dissolve in
oceans, lakes and ponds, forming bicarbonate ions and other
compounds that change water chemistry, with possible harmful
effects on aquatic organisms. In addition, bicarbonate can reenter
the atmosphere as carbon dioxide later, contributing to climate
change. Now, researchers have developed tiny “nanojars,” much
smaller than the width of a human hair, that split bicarbonate into
carbonate and capture it, as well as certain toxic anions, so the
ions can be removed and potentially recycled.
