Prediction and Treatment of Measurement Error for Total Phosphorus in Surface Water

[Objective] The research aimed to predict and treat measurement error of the total phosphorus in surface water.[Method] Total phosphorus in surface water was measured by molybdate spectrophotometry,and treatment suggestions for error problem which might occur in the measurement process were put forward.[Result] By prediction and treatment of measurement error for total phosphorus in surface water,accurate evaluation of the water body was obtained.Then,water pollution could obtain reasonable prevention and treatment.[Conclusion] Only grasping measurement method of the total phosphorus and eliminating error of each step,error which might occur could be decreased,which provided true and reliable analytic data for water resources protection.
