Designation:D85812Standard Test Methods forManganese in Water1This standard is issued under the fixed designation D858;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 These test methods cover the atomic absorption deter-mination of dissolved and total recoverable manganese inwater and certain wastewaters.Three test methods are given asfollows:Test MethodConcentration RangeSectionsAAtomic Absorption,Direct0.1 to 5 mg/L7 to 15BAtomic Absorption,Chelation-Extraction10 to 500 g/L16 to 24CAtomic Absorption,GraphiteFurnace5 to 50 g/L25 to 331.2 Test Methods A,B,and C were used successfully onreagent grade and natural waters.Other matrices used in thestudy were brine(Test Method B),effluent from a woodtreatment plant,and condensate from a medium BTU coalgasification process(Test Method C).It is the users responsi-bility to ensure the validity of a test method for waters ofuntested matrices.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system are mathematical conversions and may not beexact equivalents;therefore,each system shall be used inde-pendently of the other.1.4This 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.sectatements,see11.7,20.2,20.9,and 22.10.1.5 Former Test MethodA(Colorimetric)was discontinued.For historical information,see Appendix X1.2.Referenced Documents2.1 ASTM Standards:2D1066 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 WaterD1886 Test Methods for Nickel 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 ConstituentsD5810 Guide for Spiking into Aqueous SamplesD5847 Practice for Writing Quality Control Specificationsfor Standard Test Methods for Water Analysis3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 total recoverable manganesean arbitrary analyticalterm relating to the recoverable forms of manganese that aredeterminable by the digestion method that is included in theprocedure.3.2 Definitions:3.2.1 For definitions of terms used in these test methods,refer to Terminology D1129.1These 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 Sept.1,2012.Published September 2012.Originallyapproved in 1945.Last previous edition approved in 2007 as D858 07.DOI:10.1520/D0858-12.2For 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.*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 Although inhaled manganese dusts have been reportedto be toxic to humans,manganese normally is ingested as atrace nutrient in both food and water.Because it is consideredto be relatively nontoxic to man,as well as aquatic life,a limitof 50 g/L has been established in the EPANational SecondaryDrinking Water Regulations.This limit is based primarily onits ability to stain laundry and produce objectionable tastes inbeverages.4.3 Manganese does not occur naturally as a metal but isfound in various salts and minerals,frequently in associationwith iron compounds.Manganese is not mined in the UnitedStates except when manganese is contained in iron ores that aredeliberately used to form ferro-manganese alloys.Manganesesalts are used as fertilizer additives and are commo
