In terms of long-term safety for radioactive waste disposal, the anionic iodide (I-129) with a long half-life ($1.6{\times}10^6yr$) is of a critical importance because this radionuclide migrates in geological media with limited interactions. Various studies have been performed to retard the iodide migration. Recently, some minerals that are likely generated from waste container corrosion, have been suggested to have a considerable chemical interaction with iodide. In this study, chalcocite and mackinawite were selected as candidate minerals for underground corrosion materials, and an iodide sorption experiment were carried out. The experiment was performed under anoxic and alkaline conditions and the pH effects on the iodide sorption were investigated in the range of pH 8 to 12. The results showed that both minerals demonstrated a noticeable sorption capacity on iodide, and the distribution coefficient ($K_d$) decreased as the pH increased in the experimental condition. In addition, when the alkalinity increased higher than a pH of 12, the sorption capacity of both minerals decreased dramatically, likely due to the competition of hydroxy ions with the iodide. This result confirmed that chalcocite was an especially good sorbing media for iodide under alkaline conditions with a pH value of less than 12.

A new method for the analysis of metocurine iodide in biological fluids was developed. Metocurine iodide was quantitatively extracted with rose bengal from aqueous layer into dichloromethane layer and the amount of metocurine iodide was calculated from the amount of rose bengal which was determined by HPLC with fluorescence detector. It was possible to analyze metocurine iodide without the effect of co-prescribed drugs in the concentration range of $0.09{\sim}9.10\;{\mu}g/ml$. The detection limits of metocurine iodide in urine and blood were 0.8 and 1.2 ng at S/N=3, each respectively.

The incidence of adverse reactions to iodide contrast media was found to have increased owing to their increased use in computed tomography, but the exact reasons were unknown. Based on reported iodide contrast media adverse reactions data, it is recommended to the components of iodide contrast media before use to minimize adverse reactions. It was found that the use of iopromide and iomeprol in iodide contrast media resulted in a higher incidences of death and threat of life resulting from adverse reactions than other ingredients. Patients who are administered iodide contrast media containing iopromide and iomeprol during the computed tomography test should be carefully examined by the relevant medical professional, as the significance of gender and age varies from component to component. As multiple iodide contrast agents are available, the use of an appropriate iodide contrast media will reduce the incidence of iodide contrast media adverse reactions.

The adsorption characteristics of methyl iodide generated from the simulated off-gas stream on various adsorbents such as silver ion-exchanged zeolite (AgX), zeocarbon and activated carbon were investigated. An extensive evaluation was made on the optimal silver ion-exchanged level for the effective removal of methyl iodide at temperature up to 38$0^{\circ}C$. The degree of adsorption efficiency of methyl iodide on silver ion-exchanged zeolite is strongly dependent of silver ion-amount and process temperature. The influence of temperature, methyl iodide concentration and silver ion-exchanged level on the adsorption efficiency is closely related to the pore characteristics of adsorbents. It would be facts that the effective silver ion-exchanged level was about 10 wt%, based on the degree of silver utilization for the removal of methyl iodide.

니트로벤젠 및 m-크실렌 용액내에서 1-요오드화프로판의 용해도를 8$^{\circ}$, 15$^{\circ}$및 25$^{\circ}C$에서 요오드화칼륨이 존재할 때와 존재하지 않을 때의 두 경우에 대하여 각각 측정하여 보았다. 요오드화칼륨이 존재하지 않을 때에 m-크실렌에서 1-요오드화프로판의 용해도가 니트로벤젠에서 보다 크다. 이것은 1-요오드화프로판과 m-크실렌의 상호작용이 니트로벤젠보다 더 강하다는 것을 나타낸다. 그리고 요오드화칼륨이 존재할 경우에는 용액내에서 1-요오드화프로판과 요오드화칼륨이 불안정한 착물이 생성된다. 이 착물을 여러 경우로 가정하여 계산하여 본 결과 1:1 착물일 때, 불안정 상수 K값이 비교적 일정한 값을 나타내었다. 그러므로 1:1 착물 n-C$_3H_7I{\cdot}GaI_3$가 형성됨을 알았으며, 이 착물은 용액내에서 다음 평형식에 의해서 이루어 진다고 본다. n-C$_3H_7I{\cdot}GaI_3{\rightleftharpoons}n-C_3H_7I+1/2Ga_2I_6$ 요오드화칼륨과 1-요오드화프로판의 착물의 불안정도를 이와 대응하는 요오드화메틸과 비교하여 보았다. 또한 이 착물의 해리에 대한 엔탈피, 자유에너지 및 엔트로피 변화도 산출하였다.

Tetrachloro-p-tetraiodo-R-Fluorescein 및 sodium orthoiodohippurate등 요오드화 합물과 요오드화합물이 아닌 human serum Albumin을 요오드 표지함에 있어서 표지속도와 수율등을 비교 검토하였다. 위의 각각의 화합물들을 여러가지 다른 조건하에 있는 $Na^{131}$ I, 즉, 환원제를 함유한것, 환원제를 함유하지 않으며 거의 순수하게 131 I$^{-}$형으로 있는것, 및 환원제를 함유하지 않으며 상당량이 131 IO$_3$$^{-}$형으로 있는것 등을 써서 표지 반응시켰다. 환원제인 $Na_2$S$_2$O$_3$를 함유한 $Na^{131}$ I를 쓰는 경우는 위의 세가지 화합물들의 표지수율이 10% 내외로 매우 저조하였으며 환원제는 없지만 상당량이 $Na^{131}$ I$^{-}$로 존재하는 $Na^{131}$ I를 쓰는 경우도 50~60%의 낮은 수율이었다. 환원제가 없으며 대부분 $Na^{131}$ I$^{-}$로 존재하는 $Na^{131}$ I를 쓰는 경우에만 70~90%의 높은 표지수율을 보였다. 이들 반응에 관여하는 중간체에 대해서도 토의하였다.

수술시 근육 이완제로 사용되고 있는 metocurine iodide는 항생물질 투여환자, 중증 근무력중, 전해질 평형실조, 중증 신질환이 있는 환자 등에서는 작용이 증가되어서 상용량에서도 약화사고의 우려가 있어 규제가 필요한 약물이다. Metocurine iodide를 생체 시료중에서 분석하기 위해 rosebengal과 착제를 형성시켜 유기용매로 이온쌍 추출을 한 후, HPLC를 이용하여 rose bengal율 분석함으로써 metocurine iodide를 간접 정량하는 방법을 확립하였다. 이 방법은 뇨와 혈액증에 함유된 metocurine iodide를 0.09 - 9.10$\mu\textrm{g}$/m1농도에서 분석할 수 있었으며, 상관계수는 0.994 - 0.999로 양호한 직선성을 나타내었고, 동시 처방 약물의 영향은 거의 없었다. 뇨 및 혈액중 metocurine iodide의 검출 한계는 각각 0.8ng. 1.2ng (S =3)이었다.

This experiment was performed to investigate effects of zinc containing solution on the major normal flora Staphylococccus aureus, Streptococus mutans and Candida albicans and to observe the variation according to anionic change and concentration difference. Zinc chloride, zinc iodide and zinc acetate solution were added to werially diluted broth culture so that each final concentration might be 0.25%, 0.5%. 1%. After that, 100ul of each aliquot was spreaded on each selective media plate( Mannitol Salts Agar plate for Staphylococcus aureus, Mitis Salivarius Agar plate for Streptococcus mutans and Sabouraud Destrose Agar plate for Candida albicans). The % killing was calculated bu CFU count after incubation under the appropriate condition. 1. zinc iodide, zinc chloride, and zinc acetate solutions showed inhibitory effects on Staphylococcus aureus, Streptococcus mutans and Candida albicans. 2. The inhibitory effects on Staphylococcus aureus were ranked in order of ainc iodide, zinc chloride and zinc actate. 3. The inhibitory effects on Streptococcus mutans were ranked in orfer of zinc iodide, zinc chloride and zinc acetate. 4. the inhibitory effects on Candida albicans showed no difference among zinc iodide, zinc chloride and zinc acetate. 5. The inhibitory effects of zinc chloride and zinc acetate on Staphylococcus aureus and Streptococcus mutnas showed increasing pattern as the concentration increase. But the inhibitory effects of zinc iodide on Staphylococcus aureus and Streptococcus mutans showed no apparent difference according to concentrations and it was the case with the inhibitory effects of zinc iodide, zinc chloride and zinc acetate on Candida albicans.
