چکیده
Tin is a naturally occurring element. It is a silver-white, malleable, and somewhat ductile metal. The earth's crust contains about 2–3 ppm tin, comprising 0.0006% of the earth's crust. Major uses of tin include cans and containers, electrical, construction, and transportation. Industrially important tin compounds can be categorized as inorganic (those without a tin-carbon bond) and organic (those having a tin-carbon bond). Inorganic tin compounds are used in the glass industry, and also serve as the base for the formulation of colors, as catalysts, and in perfumes and soaps. The major commercial applications for organotin compounds are as polyvinyl chloride (PVC) heat stabilizers, biocides, catalysts, agrochemicals, and glass coatings.

متن کاملTrace determination and separation of tin (II) by floatation-spectrophotometric using kalmagyte and CTAB
ABSTRACTA novel floatation-spectrophotometric extraction method was developed for the recovery of tin (II) from aqueous samples prior to determination by UV spectrophotometric detection. The method is based on the formation of a complex between tin (II) and kalmagyte in pH=8. The complex is floated in the interface of n-hexane and aqueous phases. After removing the aqueous phase, the floated pa...

Stable Strontium. Elemental strontium (atomic number 38) occurs naturally in the earth's mantle as a mixture of four stable isotopes, Sr, Sr, Sr, and Sr, and is present everywhere in very dilute concentrations. It is very similar to calcium in its environmental and physiological behavior. Strontium is generally found in molecular compounds with other elements. Commercially important strontium m...

Ethylbenzene is widely distributed in the environment. It is primarily used for the production of styrene, which is the monomeric unit for polystyrene materials. Ethylbenzene is also used as a solvent and in the manufacture of several organic compounds other than styrene; however, these uses are very minor in comparison to the amounts used for styrene production. The production volume of ethylb...
