摘要
<正>A full automatic device to detect heavy metal Hg,Fe,Cr elements based on thin-film sensitive materials prepared on surface of light-addressable potentiometric sensors (LAPS) by means of pulsed laser deposition PLD) technique is developed. High-purity chemical compound AgI:Ag_2S:HgI synthesized were used as target of PLD,thin film sensitive to Hg~ (2+) ion was prepared on the surface of LAPS.All-solide-state chalcogenide glass ion-selective electrodes ISE) ,Fe-ISE and Cr-ISE,were also used as targets of PLD,and thin-film sensors on different LAPS sensitive to Fe~ (3+) and Cr~ (6+) ions were prepared.The heavy metal analysis device with characteristics of collect sample in-site,real-time determination,communication and multifunction software were designed.Hardware design of the device mainly includes control and measurement aspects.The detected limits of Hg,Fe,Cr ions are 3.44×10~ (-7) mol/L,6.31×10~ (-6) mol/L and 2.09×10~ (-7) mol/L,respectively.
A full automatic device to detect heavy metal Hg, Fe, Cr elements based on thin-film sensitive materials prepared on surface of light-addressable potentiometric sensors （LAPS） by means of pulsed laser deposition （PLD） technique is developed. High-purity chemical compound AgI：Ag2S：HgI synthesized were used as target of PLD, thin film sensitive to Hg^2＋ ion was prepared on the surface of LAPS. All-solide-state chaleogenide glass ion-selective electrodes （ISE）, Fe-ISE and Cr-ISE, were also used as targets of PLD, and thin-film sensors on different LAPS sensitive to Fe^3＋ and Cr^6＋ ions were prepared. The heavy metal analysis device with characteristics of collect sample in-site, real-time determination, communication and multifunction software were designed. Hardware design of the device mainly includes control and measurement aspects. The detected limits of Hg, Fe, Cr ions are 3.44×10^-7 mol/L, 6.31 × 10^-6 mol/L and 2.09× 10^-7 mol/L, respectively.
