초록

본 연구에서는 금 나노입자 콜로이드를 이용하여 safranin-O의 광촉매적 분해를 관찰하였다. 금 나노입자는 용액상에서 safranin-O의 분해 속도를 빠르게 하기 위해서 사용되었다. 금 나노입자 콜로이드는 수용액상에서 $Na_2CO_3$와 PVP 고분자(poly(vinyl pyrrolidone))를 이용하는 환원방법에 의하여 제조하였다. Safranin-O의 분해현상은 자외선(UV light)와 과산화수소($H_2O_2$)의 존재 하에서 금 나노입자 콜로이드와 염화금의 농도, 반응계의 산도(pH), 반응시간과 같은 실험조건들의 조절을 통해 연구되었다. 분해반응에 사용된 금 나노입자 콜로이드의 농도가 증가함에 따라서 염료가 분해되는 속도가 증가하였다. Safranin-O의 광산화 반응은 광학적으로 측정되었고, 금 나노입자의 기본적인 물성과 촉매 특성은 UV-Vis 광학계를 이용하여 측정되었다.

In this study, the photocatalysed degradation of safranin-O was investigated using Au colloids. Au metal nanoparticle wasused to eliminate safranin-O fast in solution. Au nanoparticles were prepared reduction method using $Na_2CO_3$ and PVP in aqueous solution. The degradation of safranin-O was examined using a variety of condition such as concentration of Au colloid or Au salt, reaction pH, and reaction time in the presence of UV light and $H_2O_2$. As the concentration of Au colloid increases, the rate of dye degradation increases. The photo-oxidation of the safranin-O was monitored spectrophotometrically. The properties of Au nanoparticles were characterized by UV-Vis spectroscopy. In addition, catalytic capacities of Au nanoparticles were also determined by UV-Vis spectroscopy.
