Application Analysis of Standard Curve Quality Control Chart in Water Quality Total Phosphorus Detection
In water quality control,excessive phosphorus in river water can cause eutrophication,which requires the use of conventional ammonium molybdate spectrophotometry for detection.However,in actual water quality total phosphorus detection,the drawing of standard curves lacks effective quality control methods,and errors in intercept and slope are not conducive to improving detection accuracy.Therefore,this article will combine the value of standard curve quality control charts in improving detection accuracy,and carry out the design and preparation of quality control chart experimental plans.Secondly,research on the application of quality control charts will be conducted from the aspects of data processing statistics,control chart drawing,analysis of judgment criteria,and discussion of slope and intercept.Finally,the precautions for this determination are proposed in the hope of ensuring high accuracy in the detection of total phosphorus.
