This study presents an environmental-friendly technique for vanadium precipitation using lysine. Experimental results indicate that 99.4 % of the vanadium is precipitated under the select reaction conditions within the lysine. During the precipitation process, the vanadium exists as negatively charged polyoxometalates, while the lysine is positively charged. The negative vanadium polyoxometalates precipitate out through electrostatic interactions. The results shown in this study introduce a new way to utilize lysine and a new treatment for polyoxometalates.

使用赖氨酸高效回收钒

本研究提出了一种使用赖氨酸沉淀钒的环保技术。实验结果表明，在选择的反应条件下，99.4% 的钒在赖氨酸内沉淀。在沉淀过程中，钒以带负电荷的多金属氧酸盐形式存在，而赖氨酸带正电荷。负钒多金属氧酸盐通过静电相互作用沉淀出来。本研究中显示的结果介绍了一种利用赖氨酸的新方法和一种新的多金属氧酸盐处理方法。
