Study on Adsorption of Cr3+ on Steel Slag by Using Batch Ezperiments

摘要：

Batch experiments were carried out to investigate heavy metal ions adsorption properties of steel slag, the results showed that steel slag could be used as an effective adsorbent to removal heavy metals such as Cr3+,Cu2+,Pb2+and Zn2+ from the aqueous solution. For the heavy metal Cr3+, the removal yield increased with increasing contact time and reached the equilibrium state within 1h; The removal of Cr3+ increased from 44% to 99% at the rang of steel slag particle size from 2.5 mesh to 80 mesh, but go on decreasing the steel slag size, the removal of Cr3+did not almost change; The equilibrium data fitted to the Langmuir and Freundlich model, However, the correlation coefficients determined for linear Freundlich models were higher than those of others.
