POLYCYCLIC AROMATIC COMPOUNDS

چکیده
|
Synthesis a well-suited coating for solid phase microextraction (SPME) fiber
is essential point due to determination trace amounts of analytes from
water and wastewater samples. So, the new coating was built onto the
porous anodized aluminum wire incorporated with layered double hydrox-ide compound and modified solvothermally with graphitic carbon nitride
and used as fiber coating for selectively analysis of polycyclic aromatic
hydrocarbons by HS-SPME method. According to the results, this coating
indicated considerable potential due to extract simultaneously trace
amounts of some carcinogenic polycyclic aromatic compounds in different
matrices. Essential parameters such as microextraction time, microextrac-tion temperature, agitation speed and ionic strength of the sample solu-tion that mainly affect the adsorption process were optimized and in the
optimum values, repeatability data of one fiber that changed between
4.7% and 7.7% for the test compounds were achieved. Detection limits for
the studied compounds were between 0.002 to 0.32mgL1
. It is a simple,
quick, and cheap approach. There is stability in the fiber in terms of tem-perature, and great recoveries are obtained by its use.
