PROBLEM TO BE SOLVED: To provide a hydrogen peroxide injection control method and apparatus in accelerated oxidation water treatment which enable proper injection control of hydrogen peroxide at appropriate timing even when the injection amount of ozone is largely changed according to the water quality ...
The HiPOx system is equipped with multiple reactors where injection of reagents can be individually controlled. This allows the HiPOx system to function in various modes: 1) using ozone only; 2) as an advanced oxidation process (AOP) using ozone and hydrogen peroxide; or 3) as a combination ...
The autosampler and tubing were washed with 2% HNO3 and ultrapure water, and the probe part was washed with 1% HCl solution and made ready for the next injection. Measurements were made at 1200 W RF power, 1 L/min carrier gas flow and 0.30 rps nebulizer pump speed, and argon gas was ...
The treatment regime consisted of; Control (water only), 2/ H2O2 + EE2, H2O2 + E E2, and EE2-only. All error bars represent standard error of the mean in all cases. results (Fig. 4) indicating all possible estrogenic intermediates had also been destroyed. Significantly...
Owing to the textile-related topics which are covered in this book, this chapter is devoted to a description of a sensor which has been developed to measure and control high hydrogen peroxide concentrations inbleaching processes, and its extension with a flow-injection system to adopt it for use...
Coupling ozone with hydrogen peroxide can increase the efficiency of a drinking water treatment line, for example in removing THM precursors. To optimize this oxidation process, the quantity of hydrogen peroxide added and the point of injection must be carefully selected....
Determination of hydrogen peroxide in sea water by flow-injection analysis with chemiluminescence detection. Anal. Chim. Acta 298, 121–128 (1994). 22. Yuan, J. C. & Shiller, A. M. Determination of subnanomolar levels of hydrogen peroxide in seawater by reagent-injection chemiluminescence ...
2-port ozone injection methodIt was verified that the ozone-hydrogen peroxide treatment (O3/H2O2) was very effective for decomposing trichloroethylene (TCE) in groundwater. The reaction efficiency of O3/H2O2 was 40% better than that of ozone treatment by using a diffuser type reactor and the ...
Briefly, mice were anaesthetized with intraperitoneal injection of mixed solution of ketamine and Xylazine (8:1 ratio), and placed on a rodent ventilator (model 687, Harvard Respirator). After thoracotomy, the left anterior descending artery (LAD) artery was identified and ligated with a 7–0 ...
These uric acid derivative have extremely strong active oxygen-eliminating activity, compared with uric acid and have high water soluble properties and are useful for treatment and prevention against diseases caused by active oxygen, e.g. brain ischemia, heart disease, renal disease, lung disease, ...
