ASTM International - ASTM UOP848-84
Nickel, Vanadium, Iron, Lead, Copper and Sodium in Gas Oils by AAS
| Organization: | ASTM International |
| Publication Date: | 29 July 2002 |
| Status: | inactive |
| Page Count: | 10 |
scope:
This method is for determining nickel, vanadium, iron, lead and copper in gas oils by graphite furnance electrothermal Atomic Absorption Spectrophotometry (GFAAS) at levels below 2000 ng/mL (approximating mass-ppb). For determination of higher levels, see UOP 800. Sodium content, expressed as g/g (mass-ppm), is determined directly by flame AAS. The lower limit of detection for all metals, including sodium, ranges from about 2 to 20 ppb depending on the element sought.
