To protect the environment from hazardous metals and promote a benign extraction method for society, pure sunflower oil is newly applied to extract mercury (Hg(I)) from synthetic water. Optimal conditions of influencing parameters have been determined via the process of solvent extraction. Its extraction mechanism is investigated, applying both theory and analysis. In addition, the reaction order and rate constant of Hg(I) extraction are obtained. Following the natural logarithm of the Arrhenius equation, the reaction rate constant, as a function of temperature, is examined. Thermodynamic parameters have also been calculated in order to identify the phenomena of extraction. Furthermore, the extraction of Hg(I) from other metals in industrial wastewater has been carried out.

为了保护环境免受有害金属的侵害并为社会推广一种良性的提取方法，新应用纯葵花籽油从合成水中提取汞 (Hg(I))。通过溶剂萃取过程确定了影响参数的最佳条件。应用理论和分析研究了其提取机理。此外，还得到了Hg(I)萃取的反应级数和速率常数。按照 Arrhenius 方程的自然对数，检查作为温度函数的反应速率常数。还计算了热力学参数以识别萃取现象。此外，还从工业废水中的其他金属中提取 Hg(I)。
