Cesium Immobilization in Soil by Ball-Milling

AbstractThis work assessed ball-milling treatment for remediation of cesium (Cs)-contaminated soil. The immobilization efficiency increases from 56.4% in the absence of treatment to 89.9, 91.5, 97.7, and 96.4% when the soil is ball milled for 30, 60, and 120 min, respectively. However, the addition of nanometallic Ca/CaO and NaH2PO4 increased the immobilization efficiency to approximately 96.4

Ball Milling-Induced Plate-like Sub-microstructured

2018-6-27  The remediation of soil contaminated by 1,1,1-trichloro-2,2-bis(4-chlorophenyl) ethane (DDT) has been a challenge. In this paper, the degradation performances of the ball milling-induced plate-like sub-microstructured zero valent iron (SMZVI) to DDT in a real soil environment is studied. It has been found that such SMZVI exhibits much higher degradation performances to DDT in soil than
