| Abstract: | Determined boiler and cooling system water total phosphorus by method according to GB/T6913 -2008, to analyze the process of testing. Mainly to study effects of the measurement conditions of the standard curve, the cuvette cleaning and the process reagents on the determination of total phosphorus. In addition, to analyze and compare effects of total phosphorus testing, from the sample acidification treatment or not, resolution time, adjusting the pH value after resolution and chromogenie time. Reduce the measurement error, simplify the detection procedure, improve the accuracy of analysis results and repeatability of testing results. |
