The Determination and Application of Hexavalent Chromium

Through the determination of Baotou high carbon ferrochrome water soluble and acid soluble hexavalent chromium, Get the following conclusion that the content of water soluble hexavalent chromium is relatively low, the concentration is 0.088mg/L, It will not cause pollution to the environment; the content of acid soluble hexavalent chromium relatively high, the concentration is 0.1867mg/L. Then measured the content of hexavalent chromium of Cement solidification of chromium slag in the acid and alkali leaching solution, it all are below the maximum allowable emission concentration of water comprehensive emission standard of 0.5mg/L, The last, the author determined the mechanical properties of cement solidification of different content of chromium slag, Draw the conclusion that the maximum dosage of chromium slag was 60%, can be used in pavement cement concrete as fine aggregate.
