Activated carbons are known to be effective adsorbents due to highly developed porosity, large surface area, variable characteristic of surface chemistry, and high degree of surface reactivity [5].
However, after the activation process, the surface has been developed into porous structure [9].
It is observed that there is a combination of mesoporous and microporous in the pore structure of durian shell activated carbon.

In [7.8], the authors note that the chemical activity of fillers depends mainly on the chemistry of their surface, i.e. the existence of superficially active centres capable of interacting with the polymer.
The formation of a fairly uniform structure in the use of glauconitic sand has increased the tensile strength of film patterns, as opposed to almost 2 times (table 2), while manifested macroheterogeneity PVC structures in the case of bituminous mineral powder resulted in a somewhat lowering of mechanical properties.

This structue is closely related to fluorite and can be considered as an ordered, defective fluorite structured materials with anion vacancies [2,3].
Compared with bulk materials, nanopowder and nano-structured materials exhibt outstanding physical and chemical properities, it, therefore, is of great significance to prepare pyrochlore oxide A2B2O7 nanopowder at low temperature.
Recently, some soft-chemistry techniques, such as coprecipitation [14] and sol-gel methods [15,16] have been attempted to prepare nanoscale pyrochlore oxides under mild condition.
The crystalline phase structure was determined by X-ray diffractometer (XRD, D/max-2550, JEOL, Japan) using CuKα radiation, λ=0.154056 nm, 40kV/300mA, scan rate of 2θ 4°/min ， scan range of (2θ) 10-80°).

Carbon precursor formed during after pyrolysis at 950 °C has amorphous structure and can’t be identified by XRD.
Morphology of amorphous carbon in all cases is predetermined by original structure of certain type of vegetable feed.
At 1150-1500 °C pyrolysis leads to amorphous-crystalline structure of the carbon.
Usage of carbon precursor with amorphous structure is the most promising.

Combined technology is the hot spot in analytical chemistry and its continuous, online, real-time analysis enhance the analysis level from trace 10-12 to ultra trace 10-15.
Soil heavy metal molecular speciation has developed hand in hand with the growth of synchrotron radiation research(The first useful synchrotron X-ray facilities were developed around 1970, about the time of Stern, Sayers, and Lytle’s modern synthesis ), including all kinds of spectral analysis technology: X-ray absorption fine structure((XAFS), including x-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS)), X-ray fluorescence spectrum analysis, x-ray scanning transmission microscopy (STXM), X-ray crystal diffraction (XRD).
XAFS spectroscopy is a unique tool for studying heavy metal speciation at the atomic or molecular scale, and the local structure around selected elements that are contained within a material.
