An N-carbamoylmethyl substituted 1,4,8,11-tetraazacyclotetradecane (cyclam) derivative was shown to exhibit favorable protonation properties together with an almost 10 6-fold selectivity for lead over calcium.
For instance, while lead must be removed from drinking water, calcium should remain because it is valuable to human health. CDIs are promising because they can eliminate selected metal ions with the help of carbon material in their electrodes. The team developed the device that can take away ...
(2018) studied the removal of calcium sulfate using two common chemical coagulants, FeCl3, and FeSO4. The amount of calcium rejected was 27.9% when FeCl3, while the rejection percentage increased to 42.7% when FeSO4 was added. Which indicated, that sulfate ion crystal was formed due to the ...
Water has dissolved minerals in it, but the amount of minerals can vary. If you have hard water, it has a high level of minerals in it, particularly calcium and magnesium. It can cause issues with your plumbing and for you as well, including the feeling that you have a film on your ...

In the water pollution environmental...
Water temperature and chemistry can affect the corrosion of metal pipes, as hot water is more corrosive than cold water, and soft water (water low is dissolved solids such as calcium and magnesium) is more corrosive than hard water. Acidic water (low pH) is also a source of corrosion, ...
Chemicals are added to water to remove residual ozone. The chemicals used include hydrogen peroxide, sodium bisulfite, and calcium thiosulfate. This method is used to remove ozone from water outside pure water system applications. Adding chemicals to water is widely used in the drinking water ind...
form of calcium apatite that is especially attractive to fluoride. When bone char is exposed to water that contains fluoride, the filter exchanges the fluoride ions for hydroxide ions, removing them from the water. This type of filter can remove up to 90% of fluoride from drinking water. ...
Although reverse osmosis supplies useful, mineral-free water for printing purposes, it does not provide the healthiest drinking water. Reverse osmosis will remove several mineral and chemical materials from water, including salt, fluoride, lead, manganese, iron, and calcium. Reverse osmosis, because ...
