2) Estimate the extraction efficiency
Organic polymers are often used as absorption agents in the extraction of organic pollutants from water samples. You already have some experience with two of these absortion agents (see first lines of the table). you now would like to estimate, if extraction is sufficently high for the other substanzens listed in the table. Please provide a short explanation for your answer. In case the given information does not allow for an answer, please also explain why.

Organic polymer I |
Organic polymer II |
3-Methylhexane |
extraction not sufficient |
extraction sufficient |
Cyclohexane |
extraction sufficient |

Dibutylether |
extraction not sufficient |

a) Heptan
|
sufficient extraction, just as with cyclohexan
|
extraction sufficient |
b) Octanal
|
extraction not sufficient, probably similar to dibuthylether |
extraction sufficient |
c) 1,4-Dichlorobenzene
|
extraction sufficient, because it is apolar and larger in size than cyclohexane.
|
extraction sufficient |
d) Hexanol
|
extraction not sufficient, because it is smaller and therefore not as efficient as methylhexanol |
extraction sufficient |
e) Pentylamin
|
probably not sufficient, because bipolar like methylhexanol and therefore smaller |
bipolar, but smaller than methylhexanol, therefore unresolved |
