The Environmental Matrix Effects of Inorganic Ions to Photo-reductive Defluorination of Perfluorooctanoic Acid Chaojie Zhang*1, a, Pei Chen 1,b, Yan Qu1,c, Qi Zhou1.d 1 College of Environmental Science and Engineering, Tongji University Shanghai 200092, PR China amyrazh@tongji.edu.cn, brichardcp212@gmail.com, cqy1755@163.com, dzhouqi@tongji.edu.cn Keywords: Perfluorooctanoic Acid, Reductive Defluorination, Inorganic Ions, Matrix Effects Abstract.
Materials and Methods Chemicals. perfluorooctanoic acid (PFOA, 90%) were purchased from Fluka (Milwaukee, WI).
As the impact to the defluorination rate, both anions and cations can inhibit the defluorination process, but anions have much greater impact than the cations to the defluorination rate. b Acknowledgement This study has been supported by the National Science Foundation Committee of PR China (Project No. 20807032, 21177094, 41271465).

The material is elastic and isotropic; The cross section of arch crown in vertical and in horizontal arch ring still be plane after deformation; The shape of gully is approximately symmetric, the geological condition were better on both sides; The deformation of foundation is small.
Fig 5 Simplified calculation sketch of cantilever Fig 6 Calculation sketch of superposition method According to the superposition principle and variable rigidities segmentation calculating method in material mechanics regard every section as a one end fixed beam, then stack every section together to conform the whole beam[5].

It has been shown that these materials do not roughen the implant surface unlike metal ultrasonic scalers [36].
Guided bone regeneration using various natural and synthetic carrier materials for local delivery of BMP-2 has been widely described in the literature [83-87].
Titanium implants coated with biomimetic calcium phosphate and BMP-2 can be augmented by bone graft materials to regenerate bone lost as a result of peri-implantitis.
