| Popis: | 97 Electrochemically modified working electrodes was used for investigating the electrochemical oxidation characteristics of ketamine with various electrochemical methods. The modified electrodes showed better electrocatalytic activity toward the oxidation of ketamine than bare ones. Those modified electrodes showed favorable electroanalytic behavior toward the oxidation of ketamine in phosphate buffer solutions which pH value varied from 4.00 to 10.00. The pH effects for the modified electrodes on peak current and peak potential were investigated, and the results showed the pH independence of later one. Under the optimized condition, the dynamic linear ranges were varied from 2.0×10-5M to 5.0×10-4M of 0.5M NaOH activated GCE, from 3.0×10-5M to 2.0×10-4M of MWCNT modified GCE. Where the detection limits were also varied from 1.0×10-5M of 0.5M HNO3 activated GCE, from 3.0×10-5M of MWCNT modified GCE. This study shows that the determination of ketamine added in soft drink can be achieved, successfully. |
