摘要：
A novel nanospheres adsorbent was successfully prepared using functionalized 1H-Pyrrole-1-ethanamine by homopolymerization. It could be easily protonated to form double-charged repeating structural units on the surface of nanospheres. The physic-chemical properties were characterized by SEM, TGA, XPS and Zeta potential. The effects of initial pH, adsorbent dosage, contact time, initial concentration, and ionic strength were studied in detail. The maximum adsorption capacity of Chromium(VI) was about 729.09mgg(-1) at room temperature. Electrostatic attraction played an important role in the adsorption process and the size of the ion group had a greater effect on the adsorption performance than the charge. [GRAPHICS] .
