Abstract Water quality-Determination of petroleum oils and animal and plant oils-Infrared spectrophotome-
,
try HJ 637-2012 called new standard revised in 2012 and replaced GB /T 16488-1996. In new standard total
oil is defined. Processing conditions of ant are changed. Measurement method of sample volume and ex-
,
traction conditions and extract dehydration are different. With ulation concentration extraction deleted the
test will be simple and easy to operate. The results of the analysis show that the sample volume measurement is
,
convenient and accurate. The detection limit was below 0. 5 mg /L and reduced the interference to the blank test.
