| Abstract | ||
| The current study established a method for preparation of polyanilie-CNT coated platinum wire (SPME Fiber) and investigated their capability to extract phenol from aqueous samples. The Platinum wires were polished with a weighing Paper, then rinsed with double- distilled water and cleaned in an ultrasonic bath and finally electrochemically treated in 0.1 M sulfuric acid by potential cycling between – 0.1and 1.5 V versus Ag/AgCl electrod until a stable cyclic voltammogram was obtained. the Stability of these type of polymers are being studied under different conditions in order to find out whether they are capable of being used for several times. Apart from being easy and inexpensive, electrochemical preparation of CNT-doped coatings of CNT- doped coatings for SPME purposes is also quite flexible and the thickness of the fibers can be controlled by the number of CV cycles. | ||
