Abstract n order to find out the mainly sources of water-soluble chromium(Ⅵ) and the total chromium for cement, it measured the contents of water-soluble chromium(Ⅵ) and the total chromium for the cement production process, including the raw materials, cement kiln calcination, cement grinding and other links. The results showed that water-soluble chromium(Ⅵ) mainly comes from the calcination stage of cement kiln; collaborative disposal will increase the total chromium content, so it is necessary to reasonably control the collaborative disposal amount; the contents of water-soluble chromium(Ⅵ) and the total chromium in the mixture should be detected regularly to avoid the content of water-soluble chromium(Ⅵ) and the total chromium exceeding the set value.
