According to chemical analysis principle, by choosing a certain amount of chromogenic agent after experiments, we manufactured the test paper of fluorine ions based on the mid-speed quantitative filter paper, and we made experiments on the standard color gamut, colored time and the repeatability of results, thus ascertained the using method and storage condition of the test paper. This test paper is easy and quick to operate; it meets the requirement of half-quantitative analysis and has preferable application value in on-site quick test.
