Method of analyzing metal component and method of manufacturing purified polymer product |
abstract |
A method of analyzing a metal component contained as an impurity in a polymer composition that contains a polymer and an organic solvent including a step (i) of preparing a dispersion by mixing the polymer composition with an acid aqueous solution, a step (ii) of separating the dispersion prepared in the step (i) into a dispersoid layer containing the polymer and a dispersion medium layer containing the metal component, and a step (iii) of quantifying the metal component contained in the dispersion medium layer separated in the step (ii). |
