to determine whether sodium polystyrene sulfonate ( sps ; kayexalate ) is effective in decreasing the absorption of lithium ( li ) and to test the assumption that li is poorly adsorbed by activated charcoal , 130 mice were administered an orogastric dose of licl ( 250 mg/kg ) followed immediately by orogastric sps ( 10 g/kg , sps group ) , activated charcoal ( 6.7 g/kg , ac group ) , or water in an equivalent volume ( control group ) .
