摘要
本文介绍一种提高凹凸棒粘土脱色力的新方法。该方法能制得脱色力与活性炭相当的活性凹凸棒粘土;这种活性凹凸棒粘土可在某些领域代替活性炭作脱色剂、除臭剂,取得显著的经济效益。
In this paper,a new process for increasing decolourant power of attapulgite clays is present- ed.Activated attapulgite clays as decolourant power as activated carbon would be made with the process.If the clays instead of activated carbon are used as decolourant and deodorisation in some applied fields,obvious economic effect will be obtained.
