| Abstract: | BOD in water could be determinated rapidly by means of micro - biofilm. The qualified sample and standard solution were investigated as the way of accuracy and precision. The standard deviation was between 1.5% and 5.2% , the value of relative error was less than 4.0%. Both results showed a good accuracy and precision, the recovery, rate of standard sample was between 95.5% and 103%. Through comparison between the biofilm and standard method, the value of relative error was between 1.5% and 10.3% , which indicated that there is no obvious difference between these two methods. It was concluded that the method showed low a detection limit, a high sensitivity and a simple and rapid properties. |
