FilmTec™ SR90 Elements contain a nanofiltration membrane that is designed to selectively remove sulfate from seawater used for waterflood injection operations in offshore oil production helping to prevent barium and strontium sulfate scale precipitation and to control/mitigate souring in reservoirs containing barium and strontium Strontium in Seawater In full strength seawater (S=35) strontium is present at approximately 90 μM (μM is short for micromolar which is a measure of the actual number of ions present as opposed to ppm (parts per million) which is a measure of the mass of ions present)

Shiny Science: A New Substitute for Hexavalent Chromium

How Electroplating Works Electroplating involves immersing the metal parts to be plated in a bath of chromium trioxide (CrO 3) typically prepared by dissolving crystalline CrO 3 in a mix of distilled water and sulfuric acid A direct current is passed through the solution and the resulting reaction leaves a deposit of chromium on the piece being plated

The Seachem Reef Status Strontium Test Kit is the first and only 10 minute strontium test The test involves separation of strontium from the sample by a highly selective extraction technique followed by a sensitive titration in 0 5 mg/L increments

Modular Component Systems (MCS) The WRT Modular Component Systems (MCS) are designed for various contaminant removal applications from 50 to 250 gallons per minute Multiple systems can be installed at a single site to achieve higher flow rates MCS treatment equipment arrives pre-assembled at the site minimizing onsite construction time

Strontium Statistics and Information

Strontium commonly occurs in nature averaging 0 034% of all igneous rock only two minerals celestite (strontium sulfate) and strontianite (strontium carbonate) however contain strontium in sufficient quantities to make its recovery practical Of the two celestite occurs much more frequently in sedimentary deposits of sufficient size to make development of mining

Bone replacement parts consisting of glass ionomer cement are superior to those made of ceramics especially since they may easily be produced and machined using common grinding and milling tools The required prosthesis part may therefore be formed of freshly mixed glass ionomer cement during the respective operation or an industrially prefabricated formed body

Strontium (Sr) and water

Strontium compounds can be water soluble Examples include strontium carbonate with a water solubility of 10 mg/L and strontium chromate with a water solubility of 9 mg/L Why is strontium present in water? The most significant strontium mineral is celestite (strontium sulphate SrSO 4) followed by strontianite (strontium carbonate SrCO 3

Because strontium is a highly reactive element it is never found in a pure form in nature Likewise the most common over-the-counter supplements are chemically bound to different molecules such as citrate lactate carbonate and gluconate Strontium ranelate is a prescription drug where the ranelate molecule is a patentable synthetic chemical

Strontium isotope analyses of enamel from the teeth of the children were measured to see whether they had been obtained from different parts of the kingdom The results supported the hypothesis in that while five of the bodies represented children born and raised in the local region two of the bodies were those of non-locals

The rubidium-strontium dating method is a radiometric dating technique used by scientists to determine the age of rocks and minerals from the quantities they contain of specific isotopes of rubidium (87 Rb) and strontium (87 Sr 86 Sr) Development of this process was aided by German chemists Otto Hahn and Fritz Strassmann who later went on to discover nuclear

•Where strontium is unavailable zirconium is the closest direct replacement for lead •Recommended levels of substitution are 3 parts zirconium metal to replace 4 parts of lead metal •Exposure to zirconium can cause detrimental health effects and occupational exposure limits are set in many countries

Strontium Strontium is a soft silver-yellow alkaline-earth metal It has three allotropic crystalline forms and in its physical and chemical properties it is similar to calcium and barium Strontium reacts vigorously with water and quickly tarnishes in air so it must be stored out of contact with air and water
