In the article that appeared on page 215 of the May 2013 issue, the following errors are noted: The caption for Figure 4 was from the original draft. The caption should read: “Figure 4. Top: Ni loading on Webster reacted with 3 mM Ni for 3, 10, 30, and 45 days and Olivier soil reacted with 3 mM Ni for 45 days. Bottom: Recoveries of Ni from sequential extractions as percentages of total adsorption amounts for different soils. Different groups indicate different reaction time.” Under the Results and Discussion section, X-ray Absorption Spectroscopy subsection: In each instance in which Figure 4 is mentioned, it should be replaced with Figure 5, and vice versa.
