- 公共卫生 公共卫生
- 水处理技术水处理技术
背景情况:
- 人类活动造成的水污染导致寄生虫疾病,包括虫感染,特别是在发展中国家.
- 污染的饮用水对公众健康构成重大风险,原因是虫蛋,如Toxcara canis.
- 有效的消毒方法对于预防水传播寄生虫疾病至关重要.
研究的目的:
- 评估臭氧和过 (臭氧-过氧化) 在饮用水中的Toxocara canis蛋无活化的有效性.
- 为了确定臭氧和过素对被虫蛋污染的水的消毒的最佳pH条件.
- 评估先进的氧化过程对控制水中寄生虫感染的潜力.
主要方法:
- 饮用水样本在实验中被污染了Toxcara canis的蛋.
- 卵子在10毫升反应器中使用臭氧和过 (臭氧-过氧化组合) 进行处理.
- 在不同的pH值 (5,7和10) 进行了治疗,暴露时间为60分钟和120分钟.
- 通过对卵的完整性和幼虫状况进行显微镜检查,量化了卵子不活化.
主要成果:
- 与单独使用臭氧相比,臭氧/过氧化的组合显示出对虫卵的优异无活化.
- 在pH10下使用过素治疗时,获得了最佳的无活化 (79.2%).

Oxidative Cleavage of Alkenes: Ozonolysis
10.2K
In ozonolysis, ozone is used to cleave a carbon–carbon double bond to form aldehydes and ketones, or carboxylic acids, depending on the work-up.
Ozone is a symmetrical bent molecule stabilized by a resonance structure.

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
