Abstract

The present invention relates to a column packing and concentrating columns for the analysis of metallic elements, wherein the column packing is formed from swollen and cleaned macroporous adsorbent resins of high, medium or non-polarity via dynamic on-column treatment or static immersion treatment using treating solution I or treating solution II; said treating solution I is a mixed aqueous solution of 0.02.about.0.06 g/L of 2-(5-bromo-2-pyridyl azo)-5-diethylamino phenol, 1.60.about.1.90 g/L of Na.sub.2B.sub.4O.sub.7.10H.sub.2O, 6.0.times.10.sup.-3.about.8.0.times.10.sup.-3 mol/L of HCl, and polyethylene glycol octyl phenyl ether with a volume percent of 0.3.about.0.8%; said treating solution II is a mixed aqueous solution of 0.04.about.0.10 g/L of 2-(5-bromo-2-pyridyl azo)-5-diethylamino phenol, 0.05.about.0.08 mol/L of glycin, 0.05.about.0.08 mol/L of NaOH, 0.010.about.0.015 mol/L of NaCl, and polyethylene glycol octyl phenyl ether with a volume percent of 0.3.about.0.8%.
