In the section titled 'In the Environment', it is mentioned that pertechnetate and iodide ions are unlikely to absorb onto the surface of rocks. I know that generally, something becoming attached to the surface of something is known as adsorbtion. Should this be changed, or is absorbtion actually what happens here?
