Aggressive chemical mediums when in contact with polymeric material cause irreversible changing of their chemical structure.
Totality of chemical processes causing chemical structure changes of the polymer and its molecular mass is called chemical destruction.
Both processes lead to the structure of compositional material destruction.
The conglomeration influence the destruction process because it proceeds in “weak place” in polymer structure (on conglomeration ties).
Polymer destruction in aggressive mediums. – M.: Chemistry, 1972.279 p

It offers the added advantage of low cost solution processing for thin film formation while for titania sol gel chemistry is complex.

Introduction Polymers come from the molecular structures formed at macro size.
Molecules bind to each other by covalent bonds to form a polymer structure, that is, structures that are formed by repeatedly repeating the structure of a molecule.
This structure is the result of the reaction of the molecule that makes up it under certain conditions.

Additional nanoparticles characterization was also studied by TEM to confirm the structure of as prepared particles.
The images show that at least, there were two structures resulted from the fabrication process, i.e.
The images have a good agreement with the result of XRD pattern, concluding that the fabricated nanoparticles consisted of TiO2 and carbon in incorporated structure.
This composite has incorporated structure between TiO2 and carbon confirmed from its XRD pattern and TEM images.

Sorption experiments Rhodamine B is a cationic dye, the structure of which is shown in Fig. 2.
The structure of methyl orange is shown in Fig. 3.
The structure of rhodamine B Fig. 3.
The pH of the dye solution is one of the most important parameters as the protonation of functional groups on adsorbent surface and the chemistry of dye molecules are strongly affected by pH of the solution [11].

Structure of obtained composites was studied by scanning electron microscopy (SEM) and X-ray diffraction (XRD).
The structure and phase composition of the composite before and after extrusion were studied by the XRD analysis with Rigaku Ultima IV diffractometer.

The structures of these compounds were elucidated as: b-sitosterolpalmitare (1), 5α, 8α-epidioxy-(22E-24R)-ergosta-6, 22-dien-3β-ol (2), 3, 7, 11, 15-tetramethyl-2-hexadecen-1-ol (3), Loliolide (4), Altertoxin I (5).
The structures of these known compounds were identified by direct comparison of their spectral data (1H NMR and 13C NMR and DEPT) with those reported values in the literatures.

Over the past century, irrigation techniques continue to improve and promote the sustainable development of regional agriculture, but some problems and difficulties are brought out on agriculture irrigation management, these problems mainly leaded by lack of related knowledge about soil-climate-crop correlation relationship, suitable development and utilization of water resources, water chemistry and soil microorganisms process change caused by excessive irrigation [1].
In order to cope with resources and environment pressure caused by the rapid development of economy and society, it is necessary to optimize the best irrigation system scientifically. 2.2 Irrigation system optimization model Irrigation system optimization are mainly limited by some factors, such as terrain, climate, the structure of crop, certainly, what’s more, there are some key factors can influence on the feasibility and rationality of irrigation system, these factors including cost, operation and management technology, irrigation efficiency[11].
