The extracti<strong>on</strong> of polycyclic aromatic hydrocarb<strong>on</strong>s<br />

(PAHs) from sedimentary organic matter by n<strong>on</strong>-i<strong>on</strong>ic<br />

surfactants with the assistance of microwave was<br />

investigated and the c<strong>on</strong>diti<strong>on</strong>s for maximum yield<br />

were determined. The results showed that the<br />

extracti<strong>on</strong> temperatures and kinetic rates have<br />

significant effects <strong>on</strong> extracti<strong>on</strong> yields of the PAHs.<br />

The optimum temperature for microwave-assisted<br />

n<strong>on</strong>-i<strong>on</strong>ic surfactant extracti<strong>on</strong> of PAHs from<br />

sedimentary organic matter was 120 o C. The optimum<br />

extracti<strong>on</strong> time for most of PAHs was at 40 minutes<br />

while a few had it at 30 minutes. The results also<br />

show that microwave-assisted n<strong>on</strong>-i<strong>on</strong>ic surfactant<br />

extracti<strong>on</strong> is a good and efficient green analytical<br />

preparatory technique for leaching PAHs from<br />

sedimentary organic matter.<br />
