摘要
在p H值为3.8的HAc-NaAC缓冲溶液中,用电化学工作站中的线性扫描法获取1.HAc-NaAc、2.HAc-NaAc和Pb(Ⅱ)、3.HAc-NaAc、HPMFP和Pb(Ⅱ)4.HAc-NaAc和HPMFP所形成的四种特性线性曲线。保持25℃恒温,将上述四种物质分别加入电解池中,在无氧条件下置于三电极体系中进行线性扫描,扫描速度为0.005V/s,在-0.35V^-0.80V(vs.SCE)范围内进行线性扫描及循环伏安法扫描,并记录扫描曲线,在-0.52V处有一个峰型很好的还原峰,应是由Pb(Ⅱ)与HPMFP所形成的混和配合物后所产生的峰电流,此峰电流是由其中心离子Pb(Ⅱ)还原产生。
In a medium of HAc - NaAc （ pH = 3.8 ）, the properties of the coordinative absorptive wave and the mechanism ofelectrode reaction of the complex of Pb （ Ⅱ ） and 1 - phenyl - 3 - methyl - 4 - （ a - furoyl） - 5 - pyrazolone （HPMctFP） arestudied by using several electrochemical methods. The linear scanning method is used to obtain 1. HAc - NaAc,2. HAc - NaAcand Pb （Ⅱ） ,3. HAc - NaAc,HPMFP and Pb （Ⅱ） 4. HAc -NaAc and HPMFP for med four properties of the linear curve. At aconstant temperature of 25 degree centigrade, the above four kinds of substances were added in an electrolytic cell, and placed ina three electrode system,under an aerobic conditions of linear scanning. The scanning speed is 0. 005V/s. In - 0.35V N -0.80V （vs. SCE） range of line scanning and cyclic vohammetry and record scanning curve, at -0.52V has a big reductionpeak,which is formed by the Pb（II） and the HPMFP complexes generated by the peak current.
