Description
Technical field
The invention belongs to phenyl ring class VOCs to absorb processing technology field, and in particular to a kind of plant absorption of phenyl ring class VOCs
Liquid and preparation method thereof.
Background technology
Plant absorption liquid is a kind of VOCs administering methods of environment-friendly type.Plant absorption liquid is 30% usually with mass fraction
Ethanol or methanol extract bark at 45 DEG C or water obtains, which has methyl mercaptan high removal rate
(97.2%), C is used13- nuclear magnetic resonance (NMR) method analyzes the extracting solution, its main active is (-) table in polyphenol mixture
Catechin (EC).By olive leaf, the waste water of olive oil product, carried with the ethanol water that mass fraction is 50% at 60 DEG C
Take 4h to obtain extract, it is found that this extract has armpit lasting deodorizing effect.Being extracted from big tangerine persimmon has removal
Machine rubbish stench, footwear are smelly, halitosis has efficient deodorant.
Polyphenols has relatively more activated groups, and reaction generation quinones substance is easily carried out with VOCs tail gas (to be had
It is pink).In addition, the part organic exhaust gas after catalytic oxidation, part chain rupture generation low molecule organic matter, portion
It is mitogenetic into soluble easily in water or organic liquor alcohols or acid, and absorbed by vegetation water.
However, its specific assimilation effect and absorption efficiency be not often good enough.If add the surface in the water of vegetation water
Active material continues to increase, and reaches a certain limit (commonly referred to as critical micelle concentration, represented with CMC), then except being enriched in boundary
It is unnecessary to form the hydrophilic group stretched in water and the micella lipophilic group being close together in water outside face.This micella is parent
What oil base was close together, this allows for the benzene class steam that it is absorbed and is wrapped among micella, so as to generate " solubilising " work
With.It is contemplated that with the increase of micella, " solubilising " effect also will increase.The least concentration for being usually formed critical micell about exists
0.01~0.4% (weight) left and right.But with aqueous solution surface reactive material be on the increase, will occur between micella
Close emigrant, form the increasing micelle of volume, they are due to being hydrophilic group towards in water, it is impossible to make benzene class steam through micelle and
Into wherein, therefore the concentration of unconfined enlarged surface active material will be nonsensical.That is, solubilization is that have
Limit.For some nonpolar organic matters, the solubility such as the organic matter of benzene,toluene,xylene etc is minimum, and is difficult
Form critical micell.In addition, the complicated component of vegetation water, layman is difficult to understand which component to containing phenyl ring class VOCs
With effective absorption, and uptake is difficult to hold.
The content of the invention
