These studies indicate that insoluble calcium chromate is more carcinogenic than soluble sodium chromate because lung cancer rates decreased after factories changed to a low or no lime production process (2).
Cr(VI) chemicals include: chromium oxide (Cr02) * ammonium dichromate (NH4Cr207) * calcium chromate (CaCr04) * chromium trioxide (chromic acid) (Cr03) * lead chromate (PbCr04) * potassium dichromate (K2Cr207) * sodium chromate (Na2Cr04) * strontium chromate (SrCr04) * and zinc chromate (Zn_Cr04):
Here, the extracted Cr is stripped mixing it with NaOH, which causes the extractant to be released as sodium chromate when it overflows this mixer into the next settler.
