The results show that the obtained nanoscale zero valent iron particles are mostly in spherical shape with less than 100 nm in size. The acid fuchsine can be removed by nanoscale zero valent iron particles efficiently. The efficiency of removing acid fuchsine from solution is increased with increasing temperature and the dosage of nanoscale zero valent iron particles and decreasing initial concentration of acid fuchsine. The mechanism of removing acid fuchsine by nanoscale zero valent iron particles may include dual functions of absorption and degradation, and the degradation may play a major role in the reaction.

It is included that 4-5 types of active sites exist in the catalytic system and the active site produced polymer with low molecular weight is easy to be activiated while TEA is used as the cocatalyst. While TIBA, the active site produced polymer with high molecular weight and seldom active site produced polymer with low one is prone to be activiated. MAO tends to activiate the active site produced polymer with middle-level molecular weight. In TEA-TIBA catalytic system, TEA and TIBA activiate the corresponding active site and the weight of every active site gradationally varied with the change of the ratio of the two cocatalysts. And the activity of the active site produced polymer with high molecular weight is proportion to the concentration of TIBA.
