Abstract
A method for the rapid analysis of trace components in a liquid, which comprises filtering said liquid through a filter paper having at least one of anion exchange functional groups and chelating ion binding functional groups, thus collecting substantially the entire amount of the objective components (anions or chelating ions) contained in said liquid on the filter paper, and analyzing the anion- or chelating ion-loaded filter paper as such or after drying, or analyzing the eluate obtained by elution of the anions or chelating ions to be analyzed from said filter paper.
