(+)-alpha-phenylglycine are significant contaminants at pharmaceutical intermediates production. To study processes for the destruction of contaminant L(+)-alpha-phenylglycine in acid aqueous solution we have investigated the transient species using both laser flash photolysis. The OH· reaction with L(+)-alpha-phenylglycine process was investigated and formed polymer. Furthermore, the results of steady-state analysis suggested that L(+)-alpha-phenylglycine removal was found to be more efficient with increasing applied dose. L(+)-alpha-phenylglycine, decreased by 44.50%, using a dose of 14kGy.

The batch removal of dye from textile dyeing wastewater by using nanooxides decorated multiwalled carbon nanotubes was studied under electron beam conditions. The effect of different nanooxides decorated multiwalled carbon nanotubes content and irradiation dosage was also investigated. The color removal efficiency was 94.9% in dose of 17.5kGy. The colour removal efficiency with Fe2O3 decorated multiwalled carbon nanotubes was similar to with TiO2 decorated multiwalled carbon nanotubues. The COD removal efficiency was 52.5% in the dose of 14.0kGy. When the irradiation dose of 17.5kGy, the COD removal efficiency was 98.2% with TiO2 decorated multiwalled carbon nanotubes.Overall, the study demonstrated that nanooxides decorated multiwalled carbon nanotubes can effectively remove color and COD from aqueous solution under irradiation.

2,2',3,3',4,4',5,5',6,6'-bromdiphenyl ether (BDE-209) solutions were irradiated with ultraviolet (UV) and electron beams. Organic compounds were fully removed by each type of radiation. The absorbed energy of the ionizing radiation (electron beams) needed for removal was much lower than that of UV photocatalysis. BDE-209 removal using the ionizing radiation was accelerated drastically by dosage. It is suggested that pH value of solution affect the decomposition rates. Radiolysis with the high pH value showed consistently high rate and high efficiency of BDE-209 removal.

In order to prove that the ability of the construction of the base course with cement-fly-ash-flushedby-seawater stabilized crushed-stones and the materials‘ spreading across the country in the future, the paper start to analyze and research the micro reaction and macro properties about the cement and fly-ash-flushed-by- seawater binder along with the cement and typical fly-ash binder, which based on a series of contrastive laboratory tests. When the mixture ratio of cement and fly-ash-flushed-by-seawater binder ,In addition, the key techniques indexes for construction ,which are controlled seriously ,It is unparalleled that the utilization of the cement and fly-ash-flushed-by-seawater stabilized crushed-stones in the construction of base course.
