You know -- the little carbon filters that take the chlorine out of the water before it gets to the ice maker.
你知道--一种小小的活性炭过滤器，用于在水流入制冰机之前过滤掉水中的氯气。So when those things end up in pools, they end up reacting with, among other things, chlorine to produce some interesting chemicals.
因此，当这些东西最终进入游泳池以后，它们加上其他东西与氯气发生反应，产生出一些有趣的化学品。The material is impermeable to air and fluids and can withstand at least eight hours of exposure to corrosive chlorine and ammonia gas.
这种材料不透气亦不渗水，且暴露于具腐蚀性的氯气与氨气下时，至少能耐得住八小时。In his view, the production of caustic soda over to Taiwan every year, 70% of the chlorine can be recycled to make plastic PVC powder.
他认为，烧碱生产地遍布台湾，每年有70%的氯气可以回收利用来制造PVC塑胶粉。Cycling economy of chlorine element would be achieved by the efficiency route of recycling chlorine from by-product hydrogen chloride.
从副产氯化氢中回收利用氯气是实现氯元素循环经济的有效途径。Open all faucets while the system is being filled. Do not close the spigot until a definite smell of chlorine is evident.
当系统被灌满以后请打开所有的水龙头，直到嗅到很明显的氯气味道时再关掉。Chlorine, sodium hypochlorite and bleaching powder used to be used as disinfectors in waterworks.
在消毒处理工艺中，氯气、次氯酸钠、漂白粉是各水厂过去常用的杀菌消毒剂。Chlorine gas can also be produced by the electrolysis of an aqueous solution of sodium chloride (saltwater).
也可以通过电解氯化钠水溶液（盐水）制取氯气。Chlorine gas was used as a chemical weapon during the first World War, under the name bertholite.
氯气在第一次世界大战中被用作化学武器当时被称作bertholite。
