摘　　要：通过对四川5个温泉水质中氧化还原电位的现场测试,得到该温泉水T-Eh变化曲线。利用物理化学原理,采用计算机模拟砷的T-Eh理论变化曲线,结果与实际曲线出现相反的变化趋势。通过研究合理地解释这种现象,同时证明温度对温泉水的氧化还原体系有较大影响,对温泉水中变价元素的测定影响非常严重。Based on the redox potential field test results of water samples from five Sichuan hot springs, the T-Eh curves were obtained. By use of physical and chemical principles and computer simulation, the authors obtained arsenic T-Eh theoretical curve and found out results and actual curves show opposite trends. Further studies provided a reasonable explanation of this phenomenon, and the great effect of temperature on the redox potential of hot spring waters was proved, and this seriously affects the determination of valence changeable elements of hot spring waters.
