Effect of Cd(II) on the ripening of ferrihydrite in alkaline media

To acquire a better understanding of the influence exerted by the presence of Cd + during the process of transforming ferrihydrite to goethite, the morphological and structural changes of several samples obtained by the addition of Cd + to a suspension of nascent goethite were explored, and their ch...
