Erratum to :  Determination of Potassium Bromate by Anion Exchange Resin Column Separation Followed by Colorimetry

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 A published procedure using Amberlite LA-2 (a liquid anion exchange resin) solutions to extract colors from food and the salt solution cellulose chromatographic technique to separate colors from each other were updated and submitted to collaborative study. Three batches of cookies and 4 purchased products were analyzed by 13 collaborators. The 3 batches of cookies contained different color mixtures requiring the selection of various procedures. The 4 purchased products were selected principally to include a variety of foods. Some results were partially deficient. The deficiencies reflect certain inadequacies in the directions as written rather than basic flaws in the method. Some improvements were suggested by the collaborators. The Associate Referee recommends that the method be further revised to correct the present inadequacies and to include some improvements, and that the revised method be submitted to another collaborative study.
