Krom doğada Cr(III) ve Cr(VI) yükseltgenme basamaklarında bulunmaktadır. Cr(III) glikoz, lipit ve protein metabolizmasında memeliler için temel element olmakla birlikte Cr(VI) hücre membranına CrO4 2- veya HCrO4 - olarak difüzlenerek biyolojik molekülleri yükseltgediğinden yüksek toksik etkiye sahiptir. Bu nedenle özellikle Cr(III) varlığında Cr(VI)’nın duyar tayinine ilişkin yöntem geliştirmek son yıllarda önem kazanmıştır. Dericilik sanayinde Cr(III) tuzlarının önemi büyüktür. Hamderiler tabaklama adı verilen işlemle amino asit ve proteinlerle kompleks oluşturan Cr(III) tuzları ile tepkimeye sokularak çevre koşullarına karşı dayanıklı hale getirilir. İşlenti ve sonrasındaki saklama koşullarında yükseltgenme sonucu deri örneklerinde Cr(VI)...
