Abstract:This article analyses the measurement metl-KKt of total phosphorus in surface water which has high suspended soilds.It also brings forward the “Ammonium Molybdate ColorationCentrifugalization’’method which can reduce the analysis error due tO high suspe nded solids.The feasibility of this metlxxt has been proved by US through analyzing many samples in the lab.


Key words:Surface water;total phosphorus(TP);sUSpended solids(ss);centrifugalizatio
