Abstract Advanced oxidation technology has the advantage of being able to efficiently degrade refractory organics, and plays an important role in the treatment of industrial organic wastewater. The article analyses its role in the purification of organic wastewater by the electrochemical method of polymer composite nano-titanium dioxide. The oxygen evolution potential of the nano titanium dioxide electrode is up to 2.8V, showing excellent electrochemical performance. Didache, Si/BDD, Nb/BDD, It/BDD electrodes and surface-modified BDD electrodes can generate strong oxidizing hydroxyl radicals on the surface of the electrodes, which are organic to phenols, dyes, pesticides, and surfactants. The degradability of wastewater is strong. Nano-titanium dioxide electrodes can degrade a variety of organic matter, with a current efficiency of >90%, and can completely mineralize organic matter. Nano-titanium dioxide electrodes have good application prospects in organic wastewater treatment.

Potassium permanganate process is an advanced oxidation technique that can provide a resolution removing organic matter in contaminated water. In this paper, the combination of composite potassium permanganate and a certain coagulant used in this process, which it was particularly suited to rapidly oxidize and degrade pollutants. It was an effective enhanced coagulation, advanced oxidation technique that could be conducted in a normal micro-polluted water environment. A series of experiment results demonstrated that the best adding quantity of composite potassium permanganate was 1.5-3.0mg/l, the best adding quantity of PFS as the coagulant was 25mg/l. Under the above conditions, potassium permanganate oxidation obviously reduced to each pollution index and greatly improved the water quality of purification of micro-polluted water. Furthermore, the organic removal rate with composite potassium permanganate was more than the unitary potassium permanganate process and the current traditional process.

ABSTRACT We investigate the reinforcing effects of both unmodified and surface modified nano titanium dioxide (TiO2) on the cure, mechanical, and thermal properties of natural rubber (NR) nanocomposites. The surface of nano TiO2 is modified by cationic surfactants cetyltrimethylammonium bromide (CTAB) and tetraethylammonium bromide (TEAB). The surface modification of nano TiO2 is characterized by Fourier transform infrared (FTIR) spectra and Field emission scanning electron microscopy (FESEM). The result reveals that surface modified nano TiO2 is much more efficient in improving the resulting properties of NR nanocomposites in comparison with unmodified nano TiO2. The excellent improvement in the properties of surface modified nano TiO2/NR composites is due to the better hydrophobicity and uniform dispersion of modified nano TiO2 within the NR matrix, as confirmed from morphological analysis. CTAB is much more effective than TEAB with respect to the properties of nano TiO2 based NR composites.

oleic acid-modified nano-titanium dioxide were synthesized by Oleic acid and tetrabutyl titanate via the sol-gel method, and characterized by IR TEM TG-DT A and XPS. Comparison with the data of the IR, the combination of carboxyl is chelating with Ti atoms. Based on the analysis of IR, TG-DTA and XPS, this paper suggests a model about the oleic acid-modified titanium dioxide nano-structure, and to provide a basis for future applications.

Oxidation Technology

Advanced oxidation technology is attracting attention as an effective method of water treatment that can degrade various organic pollutants. The combination of photocatalysis (UV) and ozone (O3) and titanium dioxide (TiO2) is a promising advanced oxidation technology. The combination of ozone, hydrogen peroxide, ultraviolet light and other oxidants for catalytic oxidation is also the current mainstream advanced oxidation technology. They can effectively degrade emerging water pollutants and alleviate water pollution problems. Titanium dioxide, hydrogen peroxide, and ozone are all popular catalysts because of their low cost, non-toxicity, strong oxidizing ability, and easy contact with various surfaces.
