Possible Environmental Risks Associated with Steel Slag: A Batch Study

摘要: Batch studies are frequently used to understand the behavior of soils, sediments, and wastes exposed to different environmental conditions. This study exposed steel slag to 0.11 M acetic acid and a mixture of 0.128 M sodium dithionite, 0.3 M sodium citrate, and 0.1 M sodium bicarbonate extraction solutions. Steel slag is going to be used as a synthetic (top) soil for mine rehabilitation. Synthetic soil is an innovative and economical alternative method to dispose of industrial wastes and by-products. When used in mine rehabilitation, synthetic (top) soil would get exposed to different environmental conditions. Hence, understanding the behavior of slag under a range of soil conditions before its use as a synthetic soil is important. To understand the mobility of metal ions from steel slag under different environmental conditions, a batch study was performed on the end-over-end mixer at 30 rpm for 48 h. Results …
