This 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.
Contaminated soils with or without additives were then mechanically treated by ball milling using a Spex Mixer/Mill mod. 8000, following the procedure reported by Montinaro et al., . Sequential extractions were then performed both on unmilled and milled soils with the purpose to assess whether the mechanical treatment could have led to changes in the distribution of …
Ball milling treatment is a promising treatment for the remediation of cesium-contaminated soil in dry conditions. Here, we studied the effect, factors and mechanisms of soil Cs immobilization by ball milling with the addition of nano-metallic Ca/CaO/NaH 2 PO 4, termed "nano-metallic Ca/PO 4."
High immobilization of soil cesium using ball milling with nano . This report shows that cesium can be immobilized in soils with an efficiency of 96 4 by ball milling with nano metallic Ca PO sub 4 In Japan the major . Mills Fisher Scientific.
When ball milling process starts, soil particles are subjected to high energetic collisions that may promote aggregation and breakage phenomena as well as accumulation of crystalline defects and vacancies (amorphization).

In the present work, the use of ball milling reactors for the remediation of lead contaminated soils was investigated. Lead immobilization was achieved without the use of additional reactants but only through the exploitation of weak transformations induced on the treated soil by mechanical loads taking place during collisions among milling media.

The ball-milled powder was recovered by washing the ball-mill and porcelain balls with pentane, and air-dried. An enzymatic attack was performed in order to remove cellulose by a commercial cellulose preparation (Onozuka/R-10) at a concentration of 1 mg ml À1 in acetate buffer solution (0.5 mol l À1, pH 4.5) at 37 8C during 24 h.
The effects of different ball milling conditions on the toxic leaching concentration and morphological distribution (BCR sequential extraction procedure) of lead in contaminated soil were analyzed, including the addition of calcium dihydrogen phosphate (Ca(H 2 PO 4) 2), ball milling time, and ball milling speed.
From Fig. 1 it clearly appears that the corresponding intrinsic immobilization efficiencies (without the application of ball milling) are relatively high (i.e. 61.5%, 92.4%, and 73.9% for SS, BS and KS, respectively), even when HA is not added, thus highlighting the intrinsic capability of soils to adsorb Pb(II). In fact, according to Weng, it is possible to assume that …
Soil samples processed with the roller mill were compared with those from a ball mill (Spex a model 8000, Spex Industries, Edison, NJ) and with a soil grinder-blender (MG Johnston a Industries, Inc, Minnetonka, MN) Particle size distribution of a Sharpsburg silty clay loam soil after being processed by each method is given in Table 1

In this study, a physical ball mill process instead of chemical extraction using toxic chemical agents was applied to remove arsenic (As) from contaminated soil. A statistical analysis was carried out to establish the optimal conditions for ball mill processing. As a result of the statistical analysis, approximately 70 % of As was removed from the soil at the following …
