일반 설명
Chromium(III) potassium sulfate dodecahydrate (Potassium chromium(III) sulfate dodecahydrate, Chrome alum) is a violet colored solid. It has been synthesized by reacting sulfur dioxide with potassium dichromate (diisolved in sulfuric acid) at -38°C. It is widely used chemical in dyeing and textile industry.
애플리케이션
Chromium(III) potassium sulfate dodecahydrate (KCr(SO4)2.12H2O) may be used for coating the slides for microscopic studies on Periplaneta americana. It may be used in the preparation of quasi-monodisperse spherical core-shell particles of Cr/α-Cr2O3.

Tumor promoters such as phorbol esters, teleocidin and okadaic acid increase the numbers of multilayered, transformed foci produced by BPV DNA-transfected C3H/10T1/2 cells. We questioned whether arsenic and chromium, which are known human carcinogens also enhance transformation of BPV DNA-transfected
