Study on decoloration of malachite green solution by the treatment of functional polymer magnetic carriers

In this paper, the decoloration effect has been researched by treating the malachite green solution with functional polymer magnetic carrier. The results show that, after 8 hourstreatment, decoloring rate of the functional polymer magnetic carrier can reach 97%, which is similar to that of the activated carbon. Furthermore, functional polymer magnetic carrier can easily be separated from water under a magnetic field outside, which effectively solved the problem of traditional decoloring materialsdifficulty to be separated from wastewater. Functional polymer magnetic carrier is a new type sorbent of dyestuff that has great prospect of exploration and application.
