| Abstract: | There is interference problem caused by the complexes staining transparent window,when spectrophotometry is applied to long-term monitoring orthophosphate.A new self-calibrating detection spectrophotometric method based on pulsating variation of optical pathlength was proposed for realizing the long-term monitoring of orthophosphate.The device with pulsating variation of optical pathlength was developed to improve the traditional spectrophotometry.The results of the comparative experiments show that the new system can effectively eliminate the interference of the complexes staining on the transparent window and improve the accuracy and reliability. |
