Abstract

It was demonstrated that trihydroxyfluorones immobilized on cellulose matrices can be used as the reagents for the rapid determination of titanium(IV) and germanium(IV). A high retention of trihydroxyfluorones on cellulose paper (78–98%) and strong chemically stable mixed fabric (74–97%) makes it possible to use these materials for the immobilization of the reagents. Mixed fabric (viscose with cotton) with immobilized phenylfluorone was used for the test determination of 0.05–5 mg/L titanium(IV) and 0.01–5 mg/L germanium( IV) by the color intensity of the reaction zone of the indicator matrix after passing 20 mL of the analyzed solution through it. A test procedure was developed for the determination of 1–200 mg/L titanium(IV) and 0.5–1000 mg/L germanium(IV) by the length of the colored zones of the test strips sealed in a polymer film. The time of the analysis is 10–15 min. The relative standard deviation of the results of the determination of germanium( IV) and titanium(IV) is no higher than 30%.
