【Abstract】 Quinalizarin ammonium-carboxylate complexing agent was synthesized and used as developer according to the principles of spectrophotometric detn. of org. F contents. Analytical conditions such as temp., solvents, and pH, were chozen after the exptl. results. An analytic method with exactitude, reliability, simplicity and rapidity was given for the detn. of org. F contents in the fluorocarbon surfactants and F-contg. textile auxiliaries.更多还原
