And because the structure of benzene nucleus as rigid and flexible alternating permutation of the hydrocarbon chain in order to facilitate the physical properties of polyacrylamidewith pingment.

又因其布局為剛性的苯核和柔性的烴鏈瓜代擺列91黄色片免费看，催促涂膜的物理板滯本能機(jī)能增不弱精品久久久久一级毛片。

The structural characteristics of the ligand of the chiral Schiff base are that the ligand has phenol hydroxyl, alcoholic hydroxyl and an imine group, one to three bromine atoms are provided on the framework of double benzene nucleus, and chiral carbon is connected with the nitrogen atom of imine.

手性西佛堿配體的結(jié)構(gòu)特征為含有酚羥基、醇羥基和亞胺基團(tuán)jjj无码高清，在萘環(huán)骨架上帶有一至三個(gè)溴原子97无码免费人妻超级碰碰碰，手性碳與亞胺的氮原子相連。

Through taken the measurements of pH, TOC, UV-Vis spectra and high-performance liquid chromatograph in the degrading process of solution ,it was found that the COD of dye solution increased, pH continuing declined and TOC reduced gradually. The UV-Vis spectra and high-performance shown that though dye molecules had been destroyed, Strong Chromophore Azo Double Bond of dye was certainly under attack, the big conjugated system was vandalized and dye molecules were decolorized degradation, but they were not completely changed into carbon dioxide and other inorganic matter by mineralization, it appeared accumulation of aromatic ring and double benzene nucleus, so it is thus evident that complete destruction of aromatic ring is more difficult than the double benzene.
