The present invention relates to a highly efficient sodium hypochlorite generation apparatus capable of decreasing disinfection by-products, which is a chlorine disinfection device for on-site generation and produces sodium hypochlorite solution by electrolyzing sodium chloride aqueous solution on site, thereby requiring no additional liquefied chlorine storage equipment or disaster prevention equipment and securing flexibility of installation and operation while not being regulated by a high-pressure gas safety control act. The highly efficient sodium hypochlorite generation apparatus of the present invention capable of decreasing disinfection by-products comprises: a diaphragm electrolytic bath comprising an anode room into which a sodium chloride aqueous solution flows, a cathode room into which water flows, and a cation exchange membrane for dividing the anode room and the cathode room; an anode water storage tank for storing chlorine gas and anode water generated by the electrolysis of the anode room; a cathode water storage tank for storing sodium hydroxide generated by the electrolysis of the cathode room and discharging hydrogen gas; and a gas/liquid contact portion in which the chlorine gas supplied from the anode water storage tank reacts with the sodium hydroxide generated at the cathode water storage tank to produce sodium hypochlorite, wherein the sodium hypochlorite generation apparatus further comprises a water-splitting electrodialysis tank for producing hydrochloric acid and sodium hydroxide using a sodium chloride aqueous solution and water to supply the same as anode water and cathode water, respectively. The present invention can provide a highly efficient sodium hypochlorite generation apparatus capable of decreasing disinfection by-products which can minimize the generation of chlorate ions (ClO3), by-products, by increasing the chlorine generation efficiency of an anode and adjusting a material balance in case of gas/liquid contact. In addition, since it is possible to provide chemicals generated using salt only to a diaphragm sodium hypochlorite generation apparatus, a highly efficient sodium hypochlorite generation apparatus capable of decreasing disinfection by-products with excellent safety and economic efficiency can be provided without using expensive chemicals that are difficult to handle.

UV-thermal dual-curable, hydroxyl- and methacrylate-functionalized urethane oligomers with different contents of unsaturated double bonds and hydroxyl groups have been synthesized and incorporated into automotive clearcoats to investigate their curing and scratch behaviors. Dynamic mechanical analyses (DMA) and FT-IR analyses were performed to observe the variation of the crosslinking networks that resulted from the chemical reactions by UV and thermal dual-curing operations with varying curing conditions, such as UV dose, thermal curing time, thermal curing temperature, and curing sequence. The scratch behaviors of dual-cured automotive clearcoats were analyzed via nano-scratch tests, accompanied with scratch images simultaneously visualized using scanning electron microscopy (SEM). The mechanical and chemical properties, such as impact resistance, pencil hardness, acid-etch resistance, and stone-chip resistance, of dual-curable clearcoats were also compared with those of UV mono-cure and 1 K thermal-cure clearcoats. The results clearly showed that the dual-curing process induced a considerably higher degree of crosslinking for the cured clearcoats prepared from the dual-curable oligomers, melamine crosslinkers, and photoinitiators. Their mechanical properties including scratch resistance were also noticeably improved via the UV-thermal curing sequence, which led to an increased conversion rate of double bonds compared with clearcoats produced using the thermal-UV curing sequence. The best conditions for high crosslinking density as well as high hardness and modulus were 2400 mJ/cm 2 at 150 °C for 10 min in the UV-thermal curing process. This result was corroborated from the reaction kinetics and surface images of the scratched clearcoats captured by SEM. © 2012 Elsevier B.V.

In this study, sulfonated poly(phenylene oxide) (SPPO) and aminated polysulfone (APSf) were synthesized for use as a cation exchange polymer and an anion exchange polymer respectively. The resulting ion exchange capacities of SPPO and APSf of 0.93 and 1.0 respectively were almost equivalent to each other. Then the ion exchange polymers were coated onto the surface of commercial carbon electrodes. Membrane capacitive deionization (MCDI) performance using these coated electrodes was tested under various operating conditions such as adsorption/desorption time, feed flow rate, and feed NaCl concentration and compared with capacitive deionization (CDI) under the same conditions. The experimental results indicate that the effluent concentration during desorption becomes higher with increased adsorption time and a lower feed flow rate. Also it was shown that the introduction of both cation and anion exchange polymers was effective in preventing the “co-ion” effect. With MCDI, a salt removal efficiency of 100% was obtained under the conditions of 5 min/1 min adsorption/desorption time and 23 mL/min feed flow rate, while with CDI the salt removal efficiency was less than 40% under the same conditions. © 2015, The Polymer Society of Korea and Springer Sciene+Business Media Dordrecht.

In this work, we studied several manufacture characteristics of various metal catalysts of Ni, Co, Cu, and Fe for the catalytic decomposition of a sodium hypochlorite solution. The metal oxide, metal hydroxide, and metal oxide-hydroxide forms were prepared and compared. Ultimately, a bead-type catalyst impregnated with a metal oxide-hydroxide mixture was manufactured and evaluated. The metal ions were oxidized and precipitated in the form of metal oxide-hydroxide or metal oxide in a hypochlorite solution, and the precipitates could decompose the hypochlorite in solution. The Ni oxide-hydroxide catalyst showed the best hypochlorite decomposition performance and was the most stable among the other metal catalysts as well as the Ni hydroxide and Ni oxide catalysts. When the Ni oxide-hydroxide catalyst was manufactured in a hypochlorite solution, an optimal mixing volume ratio of hypochlorite solution to the metal ion solution was achieved. A column packed with Ni oxide-hydroxide beads was confirmed to continuously and effectively decompose hypochlorite in seawater. © 2012 Elsevier B.V.


The present invention relates to a scrubber system having an automatic generator for an oxidizing-absorbing agent. The scrubber system comprises a scrubber and an oxidizing-absorbing agent generator. The scrubber includes a pollutant gas inlet through which air pollutants are introduced, a treated gas outlet through which the pollutant gas which has been treated is discharged, and a treated water outlet through which wastewater which has been used to treat the pollutant gas is discharged. The oxidizing-absorbing agent generator generates an oxidizing-absorbing agent by electrolyzing saline water or seawater in the scrubber, and supplies the generated oxidizing-absorbing agent into the scrubber to treat the pollutant gas introduced through the pollution gas inlet, thereby removing harmful substances.
