Abstract: Disclosed is a zeolite composite electrode for water treatment having both the electrochemical properties of a carbon electrode and the selective ion exchange properties of zeolite. The zeolite composite electrode comprises: 65 to 88 wt% of zeolite particles; 10 to 25 wt% of conductive materials including carbon; and 2 to 10 wt% of a binder for combining the zeolite particles and the conductive materials. The water treatment apparatus having the composite electrode applied thereto with the above-mentioned composition can build a high-efficiency water treatment and water softening system by merging the water softening function and electrochemical properties of zeolite and improving the regenerating method and selectivity of an existing process. Also, the water treatment apparatus is easy to operate and can be miniaturized because the water treatment apparatus uses a small amount of electric energy. And the water treatment apparatus can be realized at a lower cost than an existing technique.

Abstract: The present invention relates to a method for measuring reactive oxygen species generated by nanoparticles. A reactive oxygen species production reaction is performed by radiating light sources after injecting a reactive oxygen species probe material into nanoparticle suspension. The ionic strength of the nanoparticle suspension is enhanced by adding ion sources. At this time, the ion sources may have at least 50mM ionic strength. After the nanoparticles are separated from the suspension through natural sedimentation or centrifugation, absorbance is measured using a detector.
