On-line separation of silver with the chelate-forming resin amberlite XAD-2-PAR prior to its determination by flame atomic absorption spectrometry

Abstract
The preparation, characteristics and analytical application of the chelate-forming resin Amberlite XAD-2-PAR are described. The XAD-2-PAR resin in the presence of tetren (tetraethylenepentaamine) was applied to the on-line isolation of silver prior to its determination by flame atomic absorption spectrometry. The over-all system provides signal enhancement and can be used for the rapid and selective separation and determination of silver in copper ores.
