The purpose of this study was carried out to estimate removal possibility of IBMP and IPMP causing odor in raw water. As a result of Freundlich isotherm. IBMP was superior to IPMP in adsorptive capacity. Adsorptive capacities of activated carbon were found to be in order of Lignite, Coconut shell, and Charcoal. These were well fitted with Freundlich isotherm. According to adsorption breakthrough tests for Lignite GAC, breakthrough time of IPMP and IBMP were 5.7hr and 5.5hr, respectively. Because adsorptive capacities of target material were very different with pore size distribution, it seemed that Lignite and Coconut shell based activated carbons were recommended in order to remove door compounds.

Even if odorous compounds remained very low concentration in water, it caused strong odor. Because Geosmin and most of odorous compound had very vaporization, those were difficult to analyze with GC/MSD and Purge & Trap. So, we needed pre-treatment method for decreasing amounts of extracting solvents, improving recovery efficiencies and increasing analytical efficiencies. This study developed efficient technology for analyzing odorous compounds, using various adsorbents and extracting solvents. The optimum adsorbent was XAD resins. Especially, XAD-2, XAD-7 and XAD-2010 were superior, but XAD-2 of these and MTBE was the optimum extraction solvent. Other extraction solvent's efficiency was in order of MTBE>Dichloromethane>n-Hexane>Diethylether. The optimum NaCl dosage for increasing efficiency was 5g in liquid-liquid extraction method. The shaking time(0∼24hr) had no concern with adsorption efficiency. The optimum adsorbent was XAD-2 resin and extraction solvent was MTBE. Dosing NaCl, adsorption efficiency was increased in liquid-liquid extraction method, but NaCl has no effect on liquid-solid extraction method. In this experimental results, this method will apply to not only Geosmin but other well-known odorous compounds (2-MIB, IBMP, IPMP, TCA) and algae toxins (Mycrocystin, Anatoxin etc)

본 논문에서는 한국우주인이 국제우주정거장에서 수행한 한국우주식품 10품목에 관한 관능평가결과를 분석하였다. 개인의 기호도 차이 때문에 관능평가 점수가 낮은 품목도 있었지만 대부분 높은 점수를 받았다. 해외우주인도 한국우주식품에 관하여 높은 평가를 하고 있어 향후 한국우주식품의 국제화 가능성도 확인할 수 있었다. 향후 유인우주탐사를 대비하여 한국우주식품의 품목 다양화와 우주에서 편리하게 사용할 수 있는 기능성을 갖춘 한국우주식품용 포장지 개발이 필요하다.
