Typical Metal Selective Resins
Boron is a chemical element with symbol B and atomic number 5.
-Although boron is a relatively rare element in the earth's crust, representing only 0.001% of the crust mass, it can be highly concentrated by the action of water, in which many borates are soluble. -Humans can be exposed to boron through fruit and vegetables, water, air and consumer products. When humans consume large amounts of boron containing food, the boron concentrations in their bodies may rise to levels that can cause health problem.
Boron can infect the stomach, liver, kidneys and brains and can eventually lead to death.
SEPLITE® LSC 780 chelating resin has the high selectivity of boron from potable water.
Fluorine is a chemical element with symbol F and atomic number 9.
- It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. Small amounts of fluorine are naturally present in water, air, plants and animals.
- Humans are exposed to fluorine through food and drinking water and by breathing air. If fluorine is absorbed too frequently, it can cause tooth decay, osteoporosis and harm to kidneys, bones, nerves and muscles.
Fluorine is highly toxic to living organisms.
SEPLITE® LSC 760 chelating resin has the high selectivity of fluorine from potable water.
Magnesium is a chemical element with symbol Mg and atomic number 12.
-Elemental magnesium is a gray white lightweight metal. It tarnishes slightly when exposed to air, although, unlike the other alkali metals, an oxygen-free environment is unnecessary for storage because magnesium is protected byathin layer of oxide that is fairly impermeable and difficult to remove.
-At large oral doses magnesium may cause vomiting and diarrhoea. Magnesium compounds are usually removed from water, because of the role magnesium plays in water hardness. This is achieved by means of water softening.
SEPLITE®SC130 ion exchange resins are widely used in potable water treatment, specially for water softening of magnesium removal.
Calcium is a chemical element with symbol Ca and atomic number 20.
-Calcium is a soft gray alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca2+ is also the fifth-most- bundant dissolved ion in seawater by both molarity and mass. Free calcium metal is too reactiveto occur in nature.
-Calcium is essential for living organisms. As a major material used in mineralization of bone, teeth and shells, calcium is the most abundant metal by mass in many animals. When one takes up large amounts of calcium this may negatively influence human health.
SEPLITE® SC120 ion exchange resins are widely used in potable water treatment, specially for water softening of calcium removal.
Vanadium is a chemical element with symbol V and atomic number 23.
- It is a hard, silvery grey, ductile and malleable transition metal. The element is found only in chemically combined form in nature.
Vanadium is present in bauxite and in fossil fuel deposits such as crude oil, coal, oil shale and tar sands. In crude oil, concentrations up to 1200 ppm have been reported.
SEPLITE® LSC 710 chelating resin is designed to recovey vanadium from waste water for hydrometallurgy industry.
Chromium is a chemical element with symbol Cr and atomic number 24.
-It is a steely-gray, lustrous, hard and brittle metal.
-The relative high hardness and corrosion resistance of unalloyed chromium makes it a good surface coating, being still the most “popular" metal coating with unparalleled combined durability. A thin layer of chromium is deposited on pretreated metallic surfaces by electroplating techniques.
-SEPLITE® LSC 710 chelating resin is designed to recovey chromium from waste water for electroplating industry.
Manganese is a chemical element with symbol Mn and atomic number 25.
-It is not found as a free element in nature; it is often found in combination with iron, and in many minerals.
- Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. Manganese has no satisfactory substitute in its major applications, which are related to metallurgical alloy use.
-SEPLITE® LSC 710 chelating resin is designed to recovey manganese from waste water for hydrometallurgy industry.
Iron is a chemical element with symbol Fe and atomic number 26.
It is a metal in the first transition series. It is by mass the most common element on earth, forming much of Earth's outer and inner core. Iron is the most widely used of all the metals in its metallurgical role, accounting for 95% of worldwide metal production.
Cobalt is a chemical element with symbol Co and atomic number 27.
- Like nickel, cobalt in the Earth's crust is found only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
-The main application of cobalt is as the free metal, in production of certain high performance alloys, which are used in electroplating, owing to its attractive appearance, hardness and resistance to oxidation, and as ground coats for porcelain enamels.
Nickel is a chemical element with symbol Ni and atomic number 28
-It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile.
-The fraction of global nickel production presently used for various applications of making nickel steels, nonferrous alloys and super alloys, electroplating. Nickel is preeminently an alloy metal, and its chief use is in the nickel steels and nickel cast irons.
-SEPLITE® LSC 485 chelating resin has high selectivity to nickel. It is not effected by Fe in solution.
Copper is a chemical element with symbol Cu and atomic number 29
-It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color.
-It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. The major applications of copper are in electrical wires, roofing and plumbing, electroplating, and industrial machinery. Copper is mostly used as a pure metal but when a higher hardness is required it is combined with other elements to make an alloy such as brass and bronze.
-SEPLITE® LSC 495 chelating resin is specially designed for copper adsorption and perfectly used in copper recovery of mines, electroplating.
