【Abstract】 A water sample containing sediments is solved directly in a comparision tube of 50 mL after its resolution without film filtering,and then is centrifuged after color development by molybdate and ascorbic acid reagent,and finally its clear liquor is determined.It is indicated by a comparative experiment that this method’s sensitivity,accuracy etc can all meet the requirments of environmental monitoring code,which eliminates effectively the effect of the sediments on TP determination.更多还原
