Resin Separation

Abstract The metals Mn, Mg, Co, Cu, and Zn were separated by using an anion exchange resin column and progressively less concentrated IIC1 solution as eluting agent. The position of Mg on an anion exchange resin, not previously reported in the literature, was determined. It has been shown that by using two different ion exchange resin columns, simple hydrochloric acid solutions as eluants, and polarographic or flame photometric determinations, 12 metals can be separately estimated in an aqueous solution containing about 100 /μg of each. It is recommended that the study of ion exchange resin separation of metals found in plants be continued.

Abstract The method described involves passing an alcoholic extract of fruit product through a cation exchange resin column and then through an anion exchange resin column. Neutral fruit components are washed from the columns with alcohol and acetone solutions. Acidic components trapped on the anion column are eluted using 6N formic acid in acetone. An aliquot of the eluate is evaporated to dryness after the addition of benzene to remove the excess formic acid as an azeotrope. The residue is allowed to react with bis(trimethylsilyl)acetamide or bis(trimethylsilyl)trifluoroacetamide to form trimethylsilyl ether-ester derivatives which are detected by gas chromatography on a nonpolar (OV-1) column. Good recoveries were obtained for some common organic acids (succinic, fumarie, malic, tartaric, trans- aconitic, and citric acids) from fruit juice.
