Abstract：The present study was about the effect of temperature (5~55 ℃) and pH(3~12) value on the fluorescence characteristic of oily waste water from the export of China Petroleum & Chemical Oil Refinery. It was found that temperature only affects the fluorescence intensity but not the site of fluorescence peaks. The fluorescence peaks shift right that from 413 to 426.5 nm when the oily waste water is acid. And along with the enhancing of the acidity the fluorescence intensity ascended. The fluorescence intensity decreased with alkaline enhancing but the site of fluorescence peaks remained unchanged at 398 nm. Temperature and pH value were the two important impact factors on the fluorescence characteristic of oily waste water. If desired it needs correction and compensation on temperature and pH value. That’s expected to improve the detection accuracy of oil class and content.
