Hydrogen peroxide degrades into water and oxygen, and it is generally recognized as a safe and nonaggressive disinfectant without residues or toxic chemicals, a feature especially important for its implementation in manned spacecraft. It has been extensively and safely used as a food preservative, and the use of hydrogen peroxide as a biocide in water in long-duration space missions to complement the use of iodine and silver, and in the sanitation of vegetable crops harvested in controlled ecological life support systems prior to consumption, are both proposed. Traditional detection methods for hydrogen peroxide concentrations include the iodine method or titanium salt colorimetric method, which use a variety of reagents and need cumbersome operating steps and are thus not suitable for quantitative detection applications under the microgravity environment in manned spacecraft. In order to further realize the detection of hydrogen peroxide under a microgravity environment, vacuum-introduced liquid-core waveguide Raman (LCWR) apparatus is designed and combined with a uniform design scheme. The results showed that the developed quantitative approach for hydrogen peroxide has advantages, including a standard error of calibration of 0.22, a coefficient of determination (R²) of 0.9986, and a standard error of prediction of 0.42. This study demonstrates the great potential of the apparatus for the quantitative analysis of hydrogen peroxide in water under a microgravity environment.

LCWR开发的稳健模型结合均匀设计，用于测定微重力环境中使用的水中的过氧化氢

过氧化氢会降解为水和氧气，通常被认为是一种安全，无刺激性的消毒剂，没有残留物或有毒化学物质，这对于在载人航天器中实施尤为重要。它已被广泛，安全地用作食品防腐剂，并在长期太空飞行中在水中使用过氧化氢作为杀生物剂，以补充碘和银的使用以及在可控的生态生活中收获的蔬菜作物的卫生都提出了消费前的支持系统。传统的过氧化氢浓度检测方法包括碘法或钛盐比色法，它们使用多种试剂并且需要繁琐的操作步骤，因此不适用于载人航天器在微重力环境下的定量检测应用。为了进一步实现在微重力环境下过氧化氢的检测，设计了真空引入的液芯波导拉曼（LCWR）装置，并结合了统一的设计方案。结果表明，开发的过氧化氢定量方法具有很多优点，包括标定标准误为0.22，测定系数为（R ²）为0.9986，预测标准误为0.42。这项研究证明了该仪器在微重力环境下定量分析水中过氧化氢的巨大潜力。
