【摘要】 氯霉素在浓度为０．１ ｍ ｏｌ／Ｌ 的ＮａＯＨ 溶液中，Ｐｔ／ＧＣ 离子注入修饰电极上有一还原峰，峰电位为 － ０．８０ Ｖ（ｖｓ．ＳＣＥ），氯霉素的浓度在 １．０×１０－ ５～１．０×１０－ ３ ｍ ｏｌ／Ｌ 范围内与峰电流成正比。检出限为５．０×１０－ ６ ｍ ｏｌ／Ｌ。已用于氯霉素眼药水的测定。用线性扫描和循环伏安法研究体系的性质。实验表明，是注入的Ｐｔ催化了氯霉素的还原；体系属准可逆过程。更多还原

【Abstract】 In 0.1 mol/L NaOH solution,a sensitive reduction peak of chloramphenicol was obtained by linear sweep voltammetry at Pt/GC ion implantation modified electrode.The peak potential is -0.80V( vs .SCE).The linear relationship hold between the peak current and the chloramphenicol concentration ranging from 1.0×10 -5 ～1.0×10 -3 mol/L with a detection limit of 5.0×10 -6 mol/L.The voltammetric behaviour of the system was studied by linear sweep and cyclic voltammetry.Pt is introduced into the GCE surface to catalze the chloramphenicol reduction .The system is quasi reversible.更多还原
