Recently, the Department of Ecology Environment issued a new determination of the oil in water GB


[REVIEW] after 1 January 2019, industrial wastewater and domestic sewage water and oil will still detect infrared oil content analyzer, and for more clean water surface water, ground water and sea water, the ultraviolet spectrophotometry instruments .


Since 2013, included in the plan, the revised standard oil in water has been of concern, has sought the views of methods, including infrared spectroscopy, spectrophotometry, fluorescence spectroscopy and gravimetric method. Recently, the Department of Ecology Environment released two measurement standard oil in water, which is infrared spectrophotometry and ultraviolet spectrophotometry.

" Determination of the infrared water quality oil and animal and vegetable oils spectrophotometry (HJ 637-2018 637-2012 behalf of HJ) .pdf " for the revision of standards, the main amendments are:

Standard scope from "surface water, ground water, industrial wastewater and domestic sewage" was changed to "industrial wastewater and domestic sewage."

Edit "total oil" name "Oil"

Extractant modified from "CTC" to "tetrachlorethylene."

Petroleum oil in water by UV spectrophotometry (trial) (HJ 970-2018) .pdf to add standard,

This standard applies to surface water, groundwater and petroleum measurement seawater. Extractant is n-hexane.

That is, after January 1, 2019, industrial wastewater and domestic sewage water and oil will still detect infrared oil content analyzer, and for more clean water surface water, ground water and sea water, the use of UV spectrophotometry instrument.
