Designation:D188614Standard Test Methods forNickel in Water1This standard is issued under the fixed designation D1886;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.Scope*1.1 These test methods2,3,4cover the atomic absorptiondetermination of nickel in water and wastewaters.Three testmethods are given as follows:ConcentrationRangeSectionsTest Method AAtomic Absorption,Direct0.1 to 10 mg/L7 16Test Method BAtomic Absorption,Chelation-Extraction10 to 1000 g/L17 26Test Method CAtomic Absorption,Graphite Furnace5 to 100 g/L27 361.2 Test Methods A,B,and C have been used successfullywith reagent grade water and natural waters.Evaluation of TestMethod C was also made in condensate from a medium Btucoal gasification process.It is the users responsibility toensure the validity of these test methods for other matrices.1.3 The values stated in SI units are to be regarded asstandard.The values given in parentheses are mathematicalconversion to inch-pound units that are provided for informa-tion only and are not considered standard.1.4 This standard does not purport to address all of thesafety concerns,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.For specific hazardsstatements,see Note 5,11.8.1,21.11,23.7,and 23.10.1.5 Two former colorimetric test methods were discontin-ued.Refer to Appendix X1 for historical information.2.Referenced Documents2.1 ASTM Standards:5D858 Test Methods for Manganese in WaterD1066 Practice for Sampling SteamD1068 Test Methods for Iron in WaterD1129 Terminology Relating to WaterD1193 Specification for Reagent WaterD1687 Test Methods for Chromium in WaterD1688 Test Methods for Copper in WaterD1691 Test Methods for Zinc in WaterD2777 Practice for Determination of Precision and Bias ofApplicable Test Methods of Committee D19 on WaterD3370 Practices for Sampling Water from Closed ConduitsD3557 Test Methods for Cadmium in WaterD3558 Test Methods for Cobalt in WaterD3559 Test Methods for Lead in WaterD3919 Practice for Measuring Trace Elements in Water byGraphite Furnace Atomic Absorption SpectrophotometryD4841 Practice for Estimation of Holding Time for WaterSamples Containing Organic and Inorganic ConstituentsD5673 Test Method for Elements in Water by InductivelyCoupled PlasmaMass SpectrometryD5810 Guide for Spiking into Aqueous SamplesD5847 Practice for Writing Quality Control Specificationsfor Standard Test Methods for Water Analysis3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in these test methods,refer to Terminology D1129.3.2 Definitions of Terms Specific to This Standard:3.2.1 total recoverable nickel,na descriptive term relatingto the nickel forms recovered in the acid-digestion procedurespecified in these test methods.1These test methods are under the jurisdiction of ASTM Committee D19 onWater and are the direct responsibility of Subcommittee D19.05 on InorganicConstituents in Water.Current edition approved Oct.1,2014.Published November 2014.Originallyapproved in 1961.Last previous edition approved in 2008 as D1886 08.DOI:10.1520/D1886-14.2Chilton,J.M.,“Simultaneous Colorimetric Determination of Copper,Cobalt,and Nickel as Diethyldithiocarbamates,”Analytical Chemistry,Vol 25,1953,pp.12741275.3Platte,J.A.,and Marcy,V.M.,“ANew Tool for the Water Chemist,”IndustrialWater Engineering,May 1965.4Brown,E.,Skougstad,M.W.,and Fishman,M.J.,“Methods for Collection andAnalysis of Water Samples for Dissolved Minerals and Gases,”Techniques ofWater-Resources Investigations of the U.S.Geological Survey,Book 5,1970,p.115.5For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Significance and Use4.1 Elemental constituents in potable water,receiving water,and wastewater need to be identified for support of effectivepollution control programs.Test Methods A,B,and C providethe techniques necessary to make such measurements.4.2 Nickel is considered to be relatively nontoxic to manand a limit for nickel is not included in the EPA NationalInterim Primary Drinking Water Regulations.6The toxicity ofnickel to aquatic life indicates tolerances that vary widely andthat are influenced by species,pH,synergistic effects,and otherfactors.4.3 Nickel is a silver-white metallic element seldom occur-ring in nature in the elemental form.Nickel salts are so
