Calcium sorption behavior on 2-line ferrihydrite: aqueous Ca data from sorption envelope experiments at initial Ca concentrations of 30, 10, and 1 mM Ca (a, b, and c, respectively) conducted from pH 4 to 9. The multicomponent systems consisted of Ca and ferrihydrite or Ca, ferrihydrite, and DOM. The greater decrease in aqueous Ca in the DOM multicomponent system compared to the system without DOM is thought to occur due to ternary interactions of ferrihydrite, Ca, and DOM
