The treatment of wastewater from pulp-paper plants in China by horseradish peroxidase was investigated in this study. The effects of horseradish peroxidase and coagulants were discussed in detail. The results indicated that enzymes might improve the removal of AOX, TOC and colour for pulp\|paper wastewater and modified chitosan is far more effective than Al\-2(SO\-4)\-3 to remove AOX, TOC and colour.

Photocatalytic Activity of Titanium Dioxide Powder Fabricated from an Anodized Titanium Sheet under Ultra-Violet and Visible Light Irradiation

引用

Journal of Surface Engineered Materials and Advanced Technology 2017年第1期7卷 13-23页

A commercially pure titanium sheet with titanium carbide (TiC) precipitated in its surface layer was anodized in NH4NO3 aqueous solution and heat treated in air. The photocatalytic activity of titanium dioxide powder collected from the surface of the anodized titanium sheet was evaluated under ultra-violet and visible light irradiation. It showed relatively high photocatalytic activity in 0.1 mol/l potassium iodide solution, which was almost equal to the activity level of TiO2 powder (P-25) manufactured by Degussa Corporation. The better photocatalytic activity under ultra-violet irradiation is considered to be related to the formation of anatase type titanium dioxide. Photocatalytic activity under visible light irradiation was also observed, which was considered to be attributable to impurity doping, (carbon), in the titanium dioxide powder.

Photocatalytic Activity of Anodized Titanium Sheets under Ultra-Violet and Visible Light Irradiation

引用

Journal of Surface Engineered Materials and Advanced Technology 2014年第6期4卷 369-378页

作者： Michio Kaneko Kiyonori Tokuno Kazuo yamagishi takao Wada Tsuyoshi Hasegawa Steel Research Laboratories Nippon Steel and Sumitomo Metal Corporation Futtsu Japan Head Office Nippon Steel and Sumitomo Metal Corporation Tokyo Japan Toyo Rikagaku Kenkyusho Corporation Niigata Japan

A commercially pure titanium sheet precipitated TiC in the surface layer was fabricated by anodic oxidation in NH4NO3 solution and heat treatment in air. The fabricated sheet showed relatively high photocatalytic activity in 0.1 M KI solution, which was close to the activity level of the P-25 particle made by Degussa Corporation. It exhibited photocatalytic activity in antifungal and antivirus tests under black light irradiation. The better photocatalytic activity under black light irradiation is considered to be related to the formation of anatase and rutile type titanium dioxides and rough surface. It also showed photocatalytic activity under visible light irradiation, which is considered to be attributable to carbon and nitrogen doping in titanium dioxide.

Characterization of Surface Oxide Layers on Black-Colored Titanium

引用

Journal of Surface Engineered Materials and Advanced Technology 2018年第4期8卷 71-82页

作者： Michio Kaneko Kiyonori Tokuno Kazuo yamagishi takao Wada Tsuyoshi Hasegawa Steel Research Laboratories Nippon Steel and Sumitomo Metal Corporation Shintomi Futtsu Japan Head Office Nippon Steel and Sumitomo Metal Corporation Tokyo Japan Toyo Rikagaku Kenkyusho Corporation Tsubame Niigata Japan

Black-colored titanium was obtained by anodic oxidation of a commercially pure grade-1 titanium sheet in a 0.06 M NH4NO3 solution, followed by heat treatment at 773 K for 1 h in a vacuum furnace. The resulting oxide layer on the titanium substrate was examined by X-ray photoelectron spectroscopy, X-ray diffraction, glow discharge spectroscopy, and scanning electron microscopy. It was found that the oxide layer on the black-colored titanium sheet was several micrometers thick and mainly consisted of rutile TiO2 exhibiting a sponge like nanoporous structure. It is considered that the black-colored appearance of the titanium sheet is due to the sponge like nanoporous structure of the oxide layer absorbing the incident light. The photocatalytic activity of the black-colored titanium sheet was examined by observing the decomposition of a methylene blue (MB, C16H18N3SCl) solution under ultraviolet irradiation due to the existence of rutile TiO2. The sheet also exhibited photocatalytic activity under visible light irradiation. It is believed that the photocatalytic response upon irradiation with white light is due to carbon doping of the titanium oxide layer on the titanium substrate.
