Baseline concentrations of trace metals in grassland topsoils from West Jilin province, Northeast China Qingwei Zhang1, Sheli Chai2,a, Jing Cai2 and Lina Gao2 1Faculty of Earth Sciences,Jilin University,Changchun 130061,China 2Faculty of Geo-exploration Science and Technology,Jilin University,Changchun 130026,China achaisl@jlu.edu.cn Keywords: Baseline concentration,topsoils,trace metals,Multivariant analysis,West Jilin province Abstract: The objective of this study was to determine the baseline concentrations of trace elements in grassland topsoils from 155 soil sampling sites in West Jilin province, Northeast China, to establish the relationships between the trace metal contents and soil physicochemical properties and major oxide contents and among trace metal concentrations themselves, and to identify the possible sources of trace element in soils.
Material and Methods Site descriptions.
Reagent blanks, standard reference soil samples from the Center of National Standard Reference Material of China(GSS-1,GSS-10, GSS-11 and GSS-14) and internal control samples were also analyzed in order to monitor analytical accuracy and precision.The detection limits for trace elements (mg/kg) were: As 0.6,B 1,Cd 0.01,Co 0.7,Cr 3, Cu 1, Hg 0.005,Mn 4,Mo 0.1,Ni 2, Pb 2,Se 0.01and Zn 2.
The first association included As,Co,Cr,Cu, Mn,Mo,Ni,Zn,Al2O3 and Fe2O3,indicating the trace elements in this group were mainly associated with parent materials of soils such as Al oxides, Fe-Mn oxides and/or with the Al-bearing clay minerals, which implied that the trace elements were mainly derived from lithogenic and pedogenic processes and their concentrations in soils were mainly controlled by abundances of parent materials.

Experimental Materials Graphite powder (NGP, 99.9%, 325 mesh), Zn(CH3COO)2·2H2O (99%), H2O2 (30%), sulfuric acid (H2SO4, 98%), chlorohydric acid (HCl, 36%), sodium hydroxide (NaOH) and 4-NP were purchased from Merck Company and all chemicals precursors were used as received without further purification.
However, for the ZnO nanorods with large aspect ratio, the lower direct contact of nanorods (compare to nanoparticles grown at pH of 10 to the underlying carbon sheets and the small contact area) reduces the transfer ability of photogenerated electrons to carbon materials.
We are recently shown that for the carbon materials incorporated semiconductors (eg.

There is a lack of information on the magnetic properties of particles of such materials as powder magnetic (modified by inclusions of magnetite and maghemite) carbon sorbents intended for water purification from various kinds of impurities and, what is especially important, allowing to perform the prompt isolation of the spent sorbent – by magnetic separation.
These data, as a rule, reflect the magnetic properties not of the particles of these components themselves, but of special samples of their material.
