We have modeled the partitioning of rare earth elements (REEs) between O-donor surface groups and aqueous solutions with a simple thermodynamic treatment. Our model predicts that the Lanormalized ratios of adsorbed to dissolved REEs depend primarily on the first hydroxide binding constants of the REEs, their first and second carbonate complexing constants, and the ionic strength and carbonate concentration of the solution. For modern and for ancient seawater, we predict an overall light REE… CONTINUE READING
