Advanced Oxidation Technologies: Sustainable Solutions for Environmental Treatments

Complicated Oxidation applied sciences (AOTs) or tactics (AOPs) are quite new and cutting edge applied sciences to take away damaging and poisonous pollution. crucial techniques between them are these utilizing gentle, resembling UVC/H2O2, photo-Fenton and heterogeneous photocatalysis with TiO2. those applied sciences also are really inexpensive and as a result precious for international locations less than improvement, the place the low-budget assets are scarcer than in constructed international locations.

Cu-Zn-Al catalyst Jun Yang studied four kinds of aluminum source to prepare 1, 4 - butanediol dehydrogenation and furfural hydrogenation in the presence of Cu-Zn-Al catalyst [8]. 2) to get the copper-zinc active solution. 2. Subsequently, such alumina sol and above copper-zinc active maternal are mixed and aged for 3 h to get precipitate, which was washed, filtered and dried at 100 -110 ° C for 24h to prepare the Cu-Zn-Al catalyst (denominated as Al1 ). Following the similar steps, Cu-Zn-Al catalyst Al2 and Al3 can also be prepared by the mixing of Al2O3 powder and Al (OH) 3 powder.

Tropospheric oxalate[J]. Geophys Res Let, 10:517~520(2003). , et al. Seasonal distribution of polar organic compounds in the urban atmosphere of two large cities from the north and south of Europe [J]. Atmospheric Envirorunent,41(27):5555-5570(2007). cn Keywords: N2-fixing bacteria (NFB), DGGE, Free-living N2-fixation rate (FNR) Abstract Long-term fertilization significantly inhibited the free-living N2-fixation rate (FNR) mainly because of the increased NO3–-N. DGGE profiles and redundancy analysis (RDA) plots clearly revealed that long-term fertilizations changed the community structures of N2-fixing bacteria (NFB) due to differences in N availability and pH.

Such as vegetation damage [2], loss of species diversity [3] and soil erosion [4]. To speed up the process of ecological restoration in construction disturbance areas, a series of vegetation restoration techniques have been used including Vegetation-Growing Concrete Gunning Slope-Protected Technique [5]. The stand or fall of ecological restoration depends on plants growing. In hence, the solution of slope ecological restoration and reconstruction require an integration research including vegetation, soil physical, soil chemical and biological characteristics, and their interaction relationships.
