Hemp powders used as sorbents to remove Zn2+ ions from aqueous solution
conference contribution
posted on 2011-09-01, 00:00 authored by Y Wu, Z Zhong, J Qiu, Xungai WangSorption potential of hemp powders as sorbents converted from wasted hemp fibers for Zn2+ ions from diluted aqueous solution was explored. Spectrophotometric method was selected to determine the concentration of Zn 2+ ions in the solutions. The influence of different factors on the sorption, such as pH, amount of hemp powder applied as well as initial concentration, were studied, respectively. The obtained results show that the sorption capacity for Zn 2+ was the maximum when the pH was 5.85. Increasing the initial concentration of the solutions resulted in increased sorption capacity. Depressed uptake capacity was obtained while amount of hemp powders was increased.
