摘要
在pH=8．00的0．4mol／LNH3-NH4Cl缓冲溶液中，丙环唑与铜（Ⅰ）配位并在-0．88V（vs．SCE）处产生新的还原峰，用线性扫描循环法测定此峰为不可逆，其峰电流与丙环唑浓度在6．00×10^-6～8．00×10^-5mol／L范围内呈现良好的线性关系，相关系数r=0．9989；检出限为4．00×10^-6mol／L；测得电活性配合物丙环唑-铜（Ⅰ）中丙环唑与铜（Ⅰ）之比为2：1，稳定常数为5．81×10^12。
In a buffer solution of pH 8.00 NH3-NH4Cl （0. 4 mol/L）, a new absorptive complex wave of propiconazole-copper（Ⅰ ） complex was obtained by polarography. The peak potential （Ep） was about 0.88 V（vs. SCE）, and the peak was irreverserbile. The change of the peak height with the concentration of popiconazole was linear in the range of 6.00×10^-6 to 8. 00×10^-5 tool/L, with detection limit of 4.00×10^-5 mol/L,r=0. 9989. The composition of the complex was determined as propiconazole： Cu（Ⅰ）= 2： 1, and the condition stability eonstant was K=5.81×10^12.
