Changes in aqueous ammonium concentrations from the pore fluid of BS_0.2_50_1:1_COM and CS_0.2_50_1:1_COM versus (A) rinse treatment and (B) number of pore volumes. Ammonium removal versus rinse treatment for rinsed columns (BS_0.2_50_1:1_COM and CS_0.2_50_1:1_COM) in (C) cumulative ammonium concentration and (D) percent ammonium removal with respect to sorption concentrations obtained from unrinsed columns. Ammonium concentrations in unrinsed columns (BS_0.2_50_1:1 and CS_0.2_50_1:1) along the column length from (E) soil pore fluid and (F) sorbed ammonium in soil samples.
