摘要:
A sampling and analytical method has been developed for measurement of a starch-grafted, cross-linked sodium polyacrylate in air. Also, the method is applicable to measurement of several other polyacrylate super absorbent polymers and involves air sampling with a 37-mm PVC membrane filter, treatment of the sample with 0.07Mcupric acetate solution to form a copper-polymer precipitate, digestion of the precipitate with nitric and perchloric acids, and measurement of the copper content by inductively-coupled plasma-atomic emission spectrophotometry. The interior surface of the front piece of the filter cassette also is analyzed. This analytical method has been compared with a sodium method that currently is used. Detection limits for various super absorbent polymers ranged from 4.4 to 14 micrograms per sample.
