中文摘要 | 台灣西南沿海是烏腳病的流行區,該地區土壤中砷含量有偏高的情形,砷含量過高會經由各種途徑對人體會造成毒性與傷害,因此,環境中砷的偵測至為重要。探討與瞭解普魯士藍修飾電極在三價砷偵測上的機制,可延伸為日為土壤中砷物種偵測上的理論基礎。X-射線繞射儀與傅立葉轉換紅外線吸收光譜儀提供有力證據來探討三價砷與普魯士藍的專一性吸附機制,利用普魯士藍修飾網版印刷碳電極並可成功進行三價砷的偵測,其標準定量曲線有一良好的線性關係。此外,實際樣品的偵測結果與感應耦合電漿放射光譜儀比對也相當吻合。此研究有助於未來土壤中三價砷的偵測與毒性問題的瞭解。 |
英文摘要 | Blackfoot disease endemic village groundwater from southwestern coast area of Taiwan contains a high content of arsenic. Arsenic is toxic and harmful to human body through various pathways, so the determination of arsenic is very important. In this study, we establish a basic model for the determination of arsenic (III) in soils using a Prussian blue-modified electrode. The mechanism of the adsorption of arsenic (III) on Prussian blue can be understood by X-ray diffraction and FT-IR spectrometers. The mechanism could then be extended to the determination of arsenic (III) by a Prussian blue-modified screen-printed carbon electrode with a good linear calibration curve. The results between electrochemical analysis and inductively coupled plasma emission spectroscopy for different arsenic (III) concentration are also very consistent. The method possesses high potential as a new analytical tool to the study of arsenic (III) in soils. |
