过氧化氢对尿液处理的稳定作用研究
|
Abstract:
从尿液回收水是解决长期载人航天任务中水需求和再补给挑战的途径之一，尿液在收集和储存中需要控制微生物繁殖和保持化学稳定性。通过向新鲜尿液中添加过氧化氢及分析尿液储存过程中产生挥发性有机物结果表明：过氧化氢能抑制尿素水解而稳定尿液，也能减少尿液在处理过程中产生的挥发性有机物。这表明过氧化氢有可能成为航天任务中尿液回收稳定化处理的低风险化学品。
Recovering water from urine is one of the ways to solve the challenges of water demand and resupply in long-term manned space missions. It needs to control microbial reproduction and maintain chemical stability during urine collection and storage. By adding hydrogen peroxide to fresh urine and analyzing the volatile organic compounds produced in the urine storage process, the results show that hydrogen peroxide can inhibit the hydrolysis of urea and stabilize the urine, and it can also reduce the volatile organic compounds generated in the urine processing. This shows that hydrogen peroxide may become a low-risk chemical for urine recovery and treatment chemicals in long-term space missions.
