1、Designation:D203609(Reapproved 2015)Standard Test Methods forCyanides in Water1This standard is issued under the fixed designation D2036;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 parenthese
2、s 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.Scope1.1 These test methods cover the determination of cyanidesin water.The followi
