Water filtration system reduces amount of lead, fluoride and chlorine in tap wateringentaconnectFiltration & Separation
The method and apparatus of the present invention permits a preselected amount of liquid to be very accurately dispensed in a drop-by-drop fashion. The liquid is peristaltically pumped intermittently from a reservoir to a discharge pipe by the successive squeezing and releasing of an elastic tube ...

The proposed method was applied to determination of the fluoride ion in various water samples (tap water, river water, rain water, underground water, and hot spring water) and satisfactory results were obtained.doi:10.1006/mchj.1994.1021M. Tabata...
A high-sensitive and selective method for determining ultratrace amounts of Mn has recently been developed.The method is based on the catalytic oxidation of malachite green by potassium periodate in the presence of nitrilo triacetic acid as an activator and sodium fluoride as masking agent.Optimum ...
