The diameter of nano-particle is small and its surface energy is high. Atomic valence bond of particle surface is not saturation and surface atoms have extremely physical and chemical activity. So, nano-particle is apt to agglomerate to make difficult to bring its excellent properties to completely play and to modify polymer.

纳米粒子粒径小，表面能大，且粒子表面的原子价健处于不饱和状态，表面原子有极大的物理与化学活性，因此纳米粒子非常易于团聚和吸附，而使得其拥有的性能难以充分发挥，从而失去应有的对高分子材料的改性作用。

With the development of science and technology, sensitive, rapid, reproducible, simple and accurate analytical methods are required for the determination of trace elements in geological, biological and environmental samples.
