摘要:

The shape of expanded graphite is a netted and hollow structure.It is very easy to adsorb molecules and adsorption power is better. The research has proved:the expanded graphite had its ability to adsorb weigh oil etc. The capacity of adsorptive materials has been expressed by the iodimetric adsorption value, but the iodimetric adsorptive value of expanded graphite has not been reported until so far.The paper measures the iodimetric adsorption value by the iodimetry, and the apparatus is used easily and simply. The operation is not more difficult and the accuracy is higher, and the reagent is usual.
