渣

In this research, the concentration of PbCrO4 in the reaction can be as low as 58g-L-1 without any ill influence on the experiment. Therefore, some leachate can be used to produce yellow chrome directly without concentration.

乙酸铅或硝酸铅与代替重铬酸钠溶液的铬渣滤液反应时，其用量应高于理论值，大约为理论值的1.10～1＊倍，才能使六价铬充分反应，使生成的铬黄量达到最大值。

In conclusion, not only the methods and relative situation of extracting Cr from chrome slag but also the feasibility of producing yellow chrome by using chrome slag"s leachate were studied in this dissertation. All these study will provide necessary theoretical basis for the industrialization of producing yellow chrome from the chrome slag"s leachate.

本论文研究的创新之处在于：本研究以从铬渣中提取六价铬作为立足点，消除了解毒后的铬遇氧化条件毒性恢复的可能，利用回收的六价铬制取铬黄颜料的研究初步证明，该法不仅切实可行，而且成本低廉、效益好。
