Sets out an inductively coupled plasma-atomic emission spectrometric method for the determination of cadmium, chromium, cobalt, copper, lead, manganese, nickel and zinc extracted from soil by digestion with aqua regia.
Scope
1 SCOPE This Standard specifies an inductively coupled plasma-atomic emission spectrometric (ICPAES) method for the determination of one or more metals in aqua regia extracts of soils or related materials. Working solution concentration range is dependent upon instrument and operating conditions.
NOTE: This is an intricate procedure and should be performed only by an analyst familiar with the chemistry of the technique and the operational procedures of the instrument used.
