2、signation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determi
3、nation of total oiland grease(TOG)that can be extracted from water or waste-water samples by cyclohexane and measured by non-dispersiveIR spectroscopy from 13701380 cm-1.Treating the extractwith Florisil2to remove polar substances prior to the IRmeasurement enables determination of the total petrole

5、recomplete fraction of extracted petroleum hydrocarbon is ac-cessible by this method as compared to GC methods that use atime window for quantification,as petroleum hydrocarbonseluting outside these windows are also quantified.1.3 This method defines total oil and grease in water asmaterial that can
6、 be extracted with cyclohexane and measuredby IR absorption in the region of 13701380 cm-1(7.257.3m).Similarly,total petroleum hydrocarbon in water is definedas material that can be extracted with cyclohexane,remains inthe extract after filtration over Florisil and is measured by IRabsorption in the
7、 region of 13701380 cm-1(7.257.3 m).Theconcentration of total grease is defined as the differencebetween the total oil and grease and total petroleum hydrocar-bon concentrations.1.4 This method covers the range of 0.5 to 1000 mg/L fortotal oil and grease as well as for total petroleum hydrocarbonsan
8、d has a method detection limit(MDL)of 0.5 mg/L.Therange and method detection limit may be extended to higher orlower concentrations by adjusting the water or solvent volumeused in the liquid-liquid extraction.1.5 The values stated in SI units are to be regarded asstandard.No other units of measureme
