  • This paper presents the synthesis of ampholyte immobilized hollow-fiber membranes and adsorption characteristic of metallic ions. This is prepared by radiation induced grafting polymerization of an epoxy group containing Glycidyl methacrylate (GMA) onto an existing polyethylene porous hollow-fiber membrane. Ampholyte ion-exchanged alkalic group, $-NH_2$ (amine function) of Taurine (TAU) is reacted with glycidyl of GMA for the synthesis of stable membrane. However, Sodium sulfite (SS) membrane is also prepared by making chemical bonds with GMA of porous hollow-fiber membrane for the comparison of adsorption characteristic of metallic ions. These are called as TAU and SS membranes, respectively. It is shown that TAU membrane shows a steady flux, 0.9 m/h regardless of the density of TAU, while the flux of SS membrane decreases rapidly as the density of $SO_3H$ group increases. SS membrane showed a negligible flux. TAU membrane with the density 0.8 mmol/g shows the amount of metallic ions adsorbed in the following order, Cu > Cd > Mg > Sb > Pb. In general, TAU membrane with high density and reaction time showed the high amount of metallic ions adsorbed and flux.

  • Anionic surfactants were synthesized by using an sarcosine, taurine and fatty alcohol with varying the carbon chain length. The structure of synthesized surfactants was confirmed by $^1H$ NMR analysis. The critical micelle concentration of the synthetic anionic surfactant was $10^{-2}{\sim}10^{-4}mol/L$ and the surface tension value at the critical micelle concentration was between 21 and 39 mN/m. It was confirmed by the Ross-Miles method that the synthetic surfactant with the carbon chain of 12 showed a good foaming power and stability. In addition, the surfactant using the sacosine was found to have a good affinity in soybean oil while that using taurine in benzene. The physical properties of synthesized surfactants were determined by measuring the critical micelle concentration, foaming power and emulsifying stability.

  • 열대야에 잃어버린 입맛을 매콤한 음식으로 살려보자 '쓰러진 소도 벌떡 일으킨다'는 낙지는 영양분이 풍부한 스테미너 식품으로 저칼로리에 철분도 풍부해 빈혈예방에 좋다. 낙지에는 오징어와 같이 콜레스테롤이 들어 있으나 타우린을 함유하고 있어 이를 억제해준다. 닭볶음탕의 닭 껍질은 조리 시 미리 제거하고 살코기 위주로 섭취한다. 낙지나 닭볶음은 양념이 자극적이므로 많이 먹지 않도록 한다.
