Invention effect
According to the present invention it is possible to solve the problems in the prior art, and reach the purpose, can also carry
It is excellent for a kind of absorption property to low molecular weight compounds such as organohalogen compounds and be difficult to when logical liquid multiple is big
The porous carbon that absorption property declines occurs.
Specific implementation mode
(porous carbon)
The porous carbon of the present invention is that middle pore volume is 0.07 (cm3/ g) more than, fine pore is the differential of 0.4nm~0.6nm
Volume maximum value is 1.6 or more.
The inventors of the present invention have found：Absorption of the porous carbon with the above characteristics to low molecular weight compounds such as organohalogen compounds
It has excellent performance, and is difficult to happen the decline of absorption property when logical liquid multiple is big.
The porous carbon of the present invention has many pores (pore).Pore is divided into mesoporous, micropore, macropore.Here, mesoporous
It refer to the pore that aperture is 2nm~50nm；Micropore refers to the pore that aperture is less than 2nm；Macropore refers to that aperture is thin more than 50nm
Hole.
Since macropore can become the channel of the water containing impurity or air etc. and with being conducted into, be adsorbed in mesoporous/micro-
The function in hole, therefore macropore will have volume to a certain degree.But at most it is unfavorable for low molecular weight substance if macropore is crossed
Absorption.Micropore is effective to the absorption of low molecular weight substance, but especially when logical liquid multiple is big, becomes with what absorption property declined
Gesture.On the other hand, if middle pore volume greatly if can effectively adsorb low molecular weight substance, and even if increased in logical liquid multiple
It is also difficult to that absorption property is made to decline when to a certain degree.If also, the differential volume maximum value that fine pore is 0.4nm~0.6nm exists
1.6 or more, then it can particularly effectively adsorb low molecular weight substance.Therefore, porous carbon with the above characteristics is to organic halogenation
The absorption property of the low molecular weight compounds such as object is excellent, absorption property will not be made to decline when logical liquid multiple is big, moreover it is possible to
Enough meet arbitrary effect.
