台灣西南沿?貐^土壤中砷含量有偏高情形,砷含量過高會經由各種途徑對人體造成毒害。以X-射線繞射儀與傅立葉轉換紅外線吸收光譜儀證明普魯士藍對三價砷的孯恍晕綑C制,再以普魯士藍修飾電極搭配流動注入系統來偵測土壤三價砷,並探討堆肥對三價砷在不同土壤中吸附與脫附的影響。試驗結果得知電化學分析技術可快速、簡便且準確地偵測土壤三價砷,且結果中也指出堆肥處理會增加秀水與後里土壤對三價砷的吸附。此外,三種土壤不論有無施用堆肥,脫附百分率的大小順序爲興大>秀水>後里,其中秀水土壤雖在施用堆肥後吸附力大小明顯增加,但脫附百分率下降的情形較不明顯,顯示黏土礦物種類與含量控制三價砷的脫附行爲。
In the southwestern part of Taiwan, soil arsenic levels are high, and arsenic levels are too high to cause poisoning to humans through various routes. X-ray diffractometer and Fourier transform infrared absorption spectroscopy to prove Prussian blue trivalent arsenic halo halo B system, and then Prussian blue modified electrode with a flow injection system to detect soil trivalent arsenic, and explore the compost Effect of trivalent arsenic adsorption and desorption in different soils. The results show that electrochemical techniques can quickly and easily detect trivalent arsenic in soil, and the results also indicate that composting increases the adsorption of trivalent arsenic in Xiushui and later soils. In addition, with or without compost application, the order of desorption percentages for the three soils was Xingda> Xiushui> Houxi, in which Xiushui soil showed a significant increase in adsorption capacity after compost application, but the desorption percentage decreased less obviously Clay mineral species and content control trivalent arsenic desorption behavior.
