Polymorph Transformation of Tricalcium Silicate Doped with Heavy Metal吕阳1,2,李相国2,MA Baoguo2,De SCHUTTER Geert11. Magnel Laboratory for Concrete Research,Department of Structural Engineering,Ghent... the influence of heavy metals on the polymorph transformation of tricalcium silicate.Heavy metal(0.1wt% to 3.0wt%) of Cr,Zn,Cu,Ni and Pb(in oxides form) was added into the raw mixtures and then sintered......

to evaluate the comprehensive pollution of heavy metals. The results show that the vertical distributions of heavy metals are different. The heavy metal concentration in the reclamation soil is lower but it is still higher than the soil background value. The heavy metal concentration in the interface between the soil and tailings is the highest, the pollution degree is the strongest. The pollution......

peel xanthate; adsorption; heavy metals _____________________________________________________________________________________________________ 1 Introduction Heavy metal wastewater exists in various industries, such as metal finishing, electroplating, plastics, pigments and mining, which threatens to the environment and human lives severely[1]. Therefore, it is urgent to remove those toxic heavy......
to its electrochemical nature by using anodic intensifiers of heavy metal ions (Pb2+, Bi3+, Tl+, Hg2+ and Ag+) on the basis of hydrogen peroxide assistant leaching on three different types of materials... assistant leaching. For the five tested heavy metal ions, Bi3+and Tl+ presented co-intensifying effect on all the three materials, and Hg2+ caused co-intensifying effect on both refractory and easily......
