초록
독성화학 물질인 sarin, V-agent 및 mustard에 대한 hydroxide계(NaOH, Na2CO3, NH4OH), oxides계(H2O2, MMPP, oxone, DCCA), Cu 킬레이트계(Cu(tmen)) 화합물의 농도와 시간에 따른 독성분해 효과를 연구하였다. Hydroxide계 독성분해 물질의 농도범위에 대한 sarin의 분해효율은 NaOH의 효과가 매우 우수한 반면, Na2CO3와 NH4OH의 독성분해 효과는 미미했다. 시간에 따른 분해효율에서 sarin에 대하여 NaOH는 반응초기에 분해효율 92%를 나타낸 반면, V-agent에 대한 NaOH와 sarin에 대한 Na2CO3는 반응시간 30 min 이내에 90 ~ 100%까지의 증가를 보였다. Sarin에 대한 산화제계 물질의 분해효율은 낮은 반면에 V-agent에 대해서는 비교적 높게 나타났다. 또한 MMPP는 mustard에 대하여 매우 우수한 독성분해 물질로 나타났다. 농도와 시간에 따른 Cu 킬레이트 화합물의 분해효율은 sarin, V-agent, 그리고 mustard에 대해 전반적으로 미약했다. 결국 sarin은 NaOH, V-agent는 MMPP와 DCCA, 그리고 mustard는 MMPP로 독성분해 효율이 크게 나타나 기존에 사용되던 STB나 DS-2를 대체할 수 있었으며, 대부분의 독성분해는 반응초기에 이루어지고 있음이 밝혀졌다.
The resolving effect of hydroxides (NaOH, Na2CO3, NH4OH), oxides (H2O2, MMPP, Oxone and DCCA) and Cu-chelate (Cu(tmen)) series of compounds on the toxic chemicals, such as sarin, V-agent and mustard were investigated in terms of the concentration and reaction time of the decontamination materials. The toxicity resolving effect of NaOH along the concentration variance on sarin exhibited superior, while that effect of the rest of the materials exhibited poor. According to the reaction time, the resolving effect of NaOH on sarin reached to 92% in the beginning of the reaction, while the effect of NaOH on V-agent and that of Na2CO3 on sarin gradually increased up to 90 ~ 100% within 30 min. The resolving effect of all oxides compounds on sarin exhibits negligible, but that on V-agent is relatively high. In particular, MMPP is one of the most effective agents for mustard. Regarding on the reaction time, the most effective reaction is accomplished within few minutes. The resolving effect of Cu-chelate compounds along theh concentration and the reaction time on sarin, V-agent, and mustard is all relatively negligible. Thus, the best decontamination chemical agents are NaOH and MMPP for sarin and mustard, respectively, whereas MMPP and DCCA are the best for V-agent. Thus STB and DS-2 of which the commercial decontamination agents, may be replaced by NaOH, MMPP, or DCCA for resolving toxic chemicals. In addition, the resolving effect of the above toxicity resolving effect occurred immediately as the two materials reacted.
