ASTM D5708-11

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Test Methods for
Determination of Nickel, Vanadium, and Iron in Crude Oils
and Residual Fuels by Inductively Coupled Plasma (ICP)
1
Atomic Emission Spectrometry
This standard is issued under the fixed designation D5708; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 These test methods cover the determination of nickel, vanadium, and iron in crude oils and residual fuels by inductively
coupled plasma (ICP) atomic emission spectrometry. Two different test methods are presented.
1.2 Test MethodA(Sections 7-11 and 18-22)—ICPisusedtoanalyzeasampledissolvedinanorganicsolvent.Thistestmethod
uses oil-soluble metals for calibration and does not purport to quantitatively determine or detect insoluble particulates.
1.3 Test Method B (Sections 12-22) —ICP is used to analyze a sample that is decomposed with acid.
1.4 The concentration ranges covered by these test methods are determined by the sensitivity of the instruments, the amount
of sample taken for analysis, and the dilution volume.Aspecific statement is given in 15.2.Typically, the low concentration limits
are a few tenths of a mg/kg. Precision data are provided for the concentration ranges specified in Section 21.
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory
limitations prior to use.

3. Summary of Test Method
3.1 Test Method A—Approximately 10 g of the sample are dissolved in an organic solvent ( Warning—Combustible. Vapor is
harmful.) to give a specimen solution containing 10 % (m/m) of sample. The solution is nebulized into the plasma, and the
intensities of the emitted light at wavelengths characteristic of the analytes are measured sequentially or simultaneously. The
intensities are related to concentrations by the appropriate use of calibration data.
3.2 Test Method B—One to 20 g of sample are weighed into a beaker and decomposed with concentrated sulfuric acid
