Abstract

The invention discloses film light addressing potential sensor for measuring Fe3+ and the manufacturing method. The sensor is based on the light addressing potential sensor (LAPS), a layer of sensitive film is produced on its surface with laser pulse depositing technology. The invention synthesizes the sensitive material at first, which is used as the target of pulse laser deposition. Then it produces a fixed metal layer through magnetism control sputtering technology on LAPS, and then carries on the process of film with laser pulse depositing technology and device. The film sensor is sensitive to the Fe3+ in the liquid; it can detect the content of Fe3+.

Description

technical field

[0001] The invention relates to a method for detecting Fe 3+ Thin film photoaddressable potentiometric sensor and its preparation method. Background technique

[0002] Heavy metal ions (such as Zn 2+ , Pb 2+ 、Cd 2+ 、Cu 2+ 、Cr 6+ , Mn 5+ 、As 3+ , Fe 3+ , Hg 2+ ) can have harmful or even fatal effects on the human body, so the quantitative detection of heavy metals is of great significance in medicine, food, clinical and environmental monitoring. The current detection methods mainly include atomic absorption spectrophotometry and mass spectrometry, etc., but the equipment used in these methods is huge and expensive, requires complex pretreatment, long measurement period and skilled operators, which brings great problems in practical applications. Many inconveniences. Contents of the invention

[0003] The object of the present invention is to provide a method for detecting Fe 3+ Thin-film light-addressable potential sensor and preparation method t...
