Designation:C110910(Reapproved 2015)Standard Practice forAnalysis of Aqueous Leachates from Nuclear WasteMaterials Using Inductively Coupled Plasma-AtomicEmission Spectroscopy1This standard is issued under the fixed designation C1109;the number immediately following the designation 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 practice is applicable to the determination of lowconcentration and trace elements in aqueous leachate solutionsproduced by the leaching of nuclear waste materials,usinginductively coupled plasma-atomic emission spectroscopy(ICP-AES).1.2 The nuclear waste material may be a simulated(non-radioactive)solid waste form or an actual solid radioactivewaste material.1.3 The leachate may be deionized water or any natural orsimulated leachate solution containing less than 1%totaldissolved solids.1.4 This practice should be used by analysts experienced inthe use of ICP-AES,the interpretation of spectral and non-spectral interferences,and procedures for their correction.1.5 No detailed operating instructions are provided becauseof differences among various makes and models of suitableICP-AES instruments.Instead,the analyst shall follow theinstructions provided by the manufacturer of the particularinstrument.This test method does not address comparativeaccuracy of different devices or the precision between instru-ments of the same make and model.1.6 This practice contains notes that are explanatory and arenot part of the mandatory requirements of the method.1.7 The values stated in SI units are to be regarded as thestandard.1.8 This standard does not purport to address all of thesafety problems,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C859 Terminology Relating to Nuclear MaterialsC1009 Guide for Establishing and Maintaining a QualityAssurance Program forAnalytical Laboratories Within theNuclear IndustryC1220 Test Method for Static Leaching of Monolithic WasteForms for Disposal of Radioactive WasteD1193 Specification for Reagent WaterD7035 Test Method for Determination of Metals and Met-alloids in Airborne Particulate Matter by InductivelyCoupled Plasma Atomic Emission Spectrometry(ICP-AES)E135 Terminology Relating to Analytical Chemistry forMetals,Ores,and Related MaterialsE177 Practice for Use of the Terms Precision and Bias inASTM Test Methods2.2 ISO and European Standards:3ISO 1042 Laboratory GlasswareOne-mark VolumetricFlasksISO 3585 Borosilicate Glass 3.3PropertiesISO 8655 Piston-Operated Volumetric Instruments(6 parts)3.Terminology3.1 For definitions of pertinent terms not listed here,seeTerminology C859.3.2 Definitions:3.2.1 atomic emissioncharacteristic radiation emitted byan electronically excited atomic species.D70353.2.1.1 DiscussionIn atomic(or optical)emissionspectrometry,a very high-temperature environment,such as aplasma,is used to create excited state atoms.For analyticalpurposes,characteristic emission signals from elements in theirexcited states are then measured at specific wavelengths.1This practice is under the jurisdiction of ASTM Committee C26 on NuclearFuel Cycle and is the direct responsibility of Subcommittee C26.05 on Methods ofTest.Current edition approved June 1,2015.Published June 2015.Originallyapproved in 1988.Last previous edition approved in 2010 as C1109 10.DOI:10.1520/C1109-10R15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.2 background correctionprocess of correcting the in-tensity at an analytical wavelength for the intensity due to theunderlying spectral background of a blank.D70353.2.2.1 DiscussionDuring sample analysis,measurementsare made of the background intensity near the peak wavelengthof the analytical lines.Correction of the analytical line peakintensity to yield the net line intensity can be made bysubtraction of either(a)a single intensity measurement per-formed on the high or low wavelength side of the analyticalline(single-point background correction),or(b)an interpo-lated background intensity from background measurementsacquired on both the high and low wavelength sides of theanalytical line(double-point background correction).3.2.3 biasbetween the expectation of the test results andan accepted reference value.E
