摘要：水环境中富勒烯（C60）的污染问题那么一直是人们广泛关注的热点，若不能及时的有效控制富勒烯的扩散，那么水环境的生态平衡和各类生物包括人类的健康终将受到严重威胁。本研究旨在探讨富勒烯在自然湖泊水体中的稳定性，同时考察其溶液浓度等对富勒烯稳定性的影响。实验以我国典型不同营养条件下湖泊水体为研究对象，探索富勒烯在不同自然湖泊水体中的团聚、分散及沉降等特征，综合探究其在自然湖泊水体中的稳定性机制。实验分别采集东湖、太湖、黄海、滇池、青海湖的水，以及地表水和超纯水来模拟不同水环境，研究发现，除黄海和青海湖外，其余水样中的富勒烯稳定性高，几乎不发生团聚现象，而青海湖水样中的富勒烯会逐渐团聚，但几乎不受温度变化影响。众多水样中，黄海水样中的富勒烯稳定性最低，团聚现象明显，且在一定温度范围内，温度越高团聚体直径越大。29025

Stability of artificial nano-fullerenes in different aqueous solution
Abstract：The pollution problem of fullerenes (C60) in the water environment has been a hot topic of widespread concern. If the proliferation of fullerenes cannot be effectively controlled in time, the ecological balance of aquatic environment,even though the health of all kinds of organisms including human health will eventually be seriously threaten. The aim of our study is to investigate the stability of fullerenes in natural lake area, and to investigate the effects of the solution concentration on the stability of fullerenes. In this paper, the water under dfferent typical nutrient conditions in China was used as the research object to explore the characteristics of fullerenes’agglomeration in the water, and to explore its stability mechanism in the water. The results showed that the water of Dong Lake, Tai Lake, Yellow Sea, Dianchi Lake, Qinghai Lake, and groundwater milli-Q water were used to simulate the different water environments. The results showed that the fullerenes in most water samples had high stability except Yellow Sea and Qinghai Lake , in which almost no agglomeration phenomenon. while in the water sample from Qinghai Lake, fullerenes will gradually aggregate, at the same time, there is no change in temperature. Among the all water samples, the stability of the fullerenes in the water samples from Yellow Sea is the lowest, where the agglomeration phenomenon is obvious, meanwhile in the range of temperature, the higher the temperature, the higher the diameter of the aggregation.
