| Abstract: | Experiment was performed to study interferential factors of anionic surfactants determination in water and wastewater by phenanthroline extraction spectrophotometric method.The interference factors were discussed in different conditions of the test results,the influence degree and removal measurement from design options including lower temperature,turbidity with color and immiscible emulsification.It made suggestion for the interferential factors removal such as to keep suitable environmental temperature in the determination to ensure color reaction completely,to eliminate interference by colorimetric（turbidity） correction,and to break the emulsification by drying organic phase with decahedrons sodium sulfate powder. |
