HEAVY METAL EXTRACTION METHOD, AND HEAVY METAL QUANTITY DETERMINATION METHOD USING THE SAME

摘要

<P>PROBLEM TO BE SOLVED: To provide a heavy metal extraction method wherein quantitative analysis and qualitative analysis can be performed with high sensitivity, even for trace amounts of heavy metals. Ž<P>SOLUTION: This heavy metal extraction method includes an adsorption process for allowing a cation-exchange resin to adsorb a heavy metal in a liquid sample; a first removal process for removing a heavy metal other than an extraction object from the cation-exchange resin by using a cleaning reagent for eluting a heavy metal other than the extraction object; and a first elution process for eluting the heavy metal from the cation-exchange resin by using an elution reagent for eluting the heavy metal which is the extraction object. Consequently, quantitative analysis and qualitative analysis can be performed at a high sensitivity, even for trace amounts of heavy metals. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
