Figure 4

Dissolved concentrations of arsenic(III) [As(III)] or arsenic(V) [As(V)] and phosphate in ad-sorptive equilibrium with hydrous ferric oxide plotted against pH computed using the adsorption model of Dzombak and Morel (Ref. 58) at the total arsenic (dissolved plus adsorbed, AsTOT), total phosphate (PTOT), and adsorption site (Sites) concentrations indicated. Values used in the computations are presented in Appendix 2.
