摘要： The present invention includes a novel salt-free water softening method that utilizes an exchange medium (such as a gel exchange polymer, a macroporous exchange polymer, or an inorganic cation exchanger) that is pre-loaded with a polyvalent cation that has low solubility in aqueous phase at nearly neutral pH. The method of the invention does not require use of a sodium salt or mineral acid in the regeneration of the exchange medium.

摘要： A process for treating feed water for desalination, the process comprising: (a) removing one or more polyvalent anions from the feed water by feeding the feed water into a bed comprising one or more anion exchange resins under conditions sufficient to exchange the polyvalent ions in the feed water with one or more monovalent anions in the resin; and (b) regenerating the bed by feeding a brine stream into the bed under conditions sufficient to exchange one or more polyvalent anions in the resins with one or more monovalent anions in the brine stream.
摘要翻译：一种用于处理用于脱盐的给水的方法，所述方法包括：（a）通过在足以交换多价离子的条件下将进料水进料到包含一种或多种阴离子交换树脂的床中，从而将来自进料水的一种或多种多价阴离子在树脂中具有一种或多种一价阴离子的给水; 和（b）通过在足以在树脂中与盐水中的一种或多种单价阴离子交换一种或多种多价阴离子的条件下将盐水流进入床中来再生床。

摘要： Methods for rapid sensing of dissolved toxic heavy metals use a hybrid inorganic material ("HIM"), which is synthesized from hydrated iron oxide ("HFO") and calcium magnesium silicate. HIM thus synthesized is used in sensing dissolved toxic heavy metals. Water containing toxic heavy metals ( e.g ., lead, copper, zinc, nickel, etc.) is passed through a sorbent bed of HIM, whereupon it shows a sharp drop in pH after a certain length of time. The presence of HFO and calcium magnesium silicates in HIM synergistically provide a precipitous drop in pH, which is characteristic of the concentration and type of toxic heavy metal. Therefore, observing a change in pH indicates the presence and identity of heavy metal ions in a test water sample.
摘要翻译：用于快速检测溶解的有毒重金属的方法使用由水合氧化铁（“HFO”）和硅酸钙镁合成的杂化无机材料（“HIM”）。因此合成的HIM用于检测溶解的有毒重金属。含有有毒重金属（例如铅，铜，锌，镍等）的水通过HIM的吸附剂床，于是在一段时间后，pH值显着下降。在HIM中HFO和硅酸镁镁的存在协同地提供了pH的急剧下降，这是有毒重金属的浓度和类型的特征。因此，观察pH值的变化表明测试水样品中重金属离子的存在和一致性。
