摘要: Batch studies are frequently used to understand the behavior of soils, sediments, and wastes exposed different environmental conditions. This study steel slag 0.11 M acetic acid a mixture 0.128 sodium dithionite, 0.3 citrate, 0.1 bicarbonate extraction solutions. Steel is going be as synthetic (top) soil for mine rehabilitation. Synthetic an innovative economical alternative method dispose industrial by-products. When in rehabilitation, would get Hence, understanding under range conditions before its use important. To mobility metal ions from conditions, batch was performed on end-over-end mixer at 30 rpm 48 h. Results depicted that being solution enhanced heavy metals. In acidic concentration trend Mn > Pb Al Ba Cr Zn Ni Cd Cu sodium-rich (saline) Concentrations Al, Ba, Cr, Fe, Mn, more saline compared fractions. These results will assist predicting impact fate toxic metals released into system. paper discuss possible reasons risks associated with soil.
