Problems solved by technology

However, the above-mentioned detection methods are relatively cumbersome in operation steps, expensive in use, require high professional skills of inspectors, and are sometimes interfered by other ions (such as chloride ions and sulfate ions), resulting in relatively large errors. Issues such as not being intuitive and fast enough limit the use of these methods

Abstract

The invention discloses a platinum complex and a preparation method and application thereof, and relates to the technical field of chemical analysis and detection. The preparation method of the platinum complex comprises the steps: using potassium tetrachloroplatinate as a raw material, and performing compound coordination on potassium tetrachloroplatinate with 2-phenylpyridine and 1,10-phenanthroline so as to obtain the platinum complex which is labeled as Pt-LZU. The invention provides a probe for detecting perchlorate ions in an aqueous solution, and the probe comprises the platinum complex. The invention also provides the application of the platinum complex in detection of perchlorate ions in an aqueous solution. Through the platinum complex probe Pt-LZU which is designed and synthesized, the perchlorate ions in the aqueous phase can be recognized with single selectivity and high sensitivity, and furthermore, the platinum complex probe Pt-LZU which is designed and synthesized by using the method has a simple structure, a simple synthesis method and a good application prospect in detection of the perchlorate ions; and the platinum complex has a chemical structure as follows.

Description

Technical field [0001] The invention relates to the technical field of chemical analysis and detection, in particular to a platinum complex and its preparation method and application. Background technique [0002] Perchloric acid and its metal salts are important industrial raw materials. As an important inorganic oxidant, they are widely used in analytical reagents, leather processing, paint production, printing and dyeing, explosives, and rockets used for launching spacecraft, artificial satellites and missiles. Fuel and other fields (Environ. Sci. Technol. 1999, 33(19), 3469-3472). Since most perchlorates have good water solubility and are not easily adsorbed on other substances, once they enter the environment with water, they will easily penetrate into soil, groundwater and irrigation water, and will inevitably begin to spread among various environmental systems. , The formation of persistent and mobile pollution, deteriorating the ecological environment. The charge and io...
