摘要
在0.05 mol/L KCl底液中,β-环糊精(β-CD)-六次甲基四胺超分子络合物在2.5次微分极谱仪上于-0.78V(vs.SCE)处产生吸附还原波,峰形对称且稳定,其峰电流与六次甲基四胺浓度在4.0×10-4-1.0×10～mol/L之间呈良好线性关系;检出限为1.5×10-4mol/L。应用该法测定了有机工业产品六次甲基四胺,并与传统方法进行了比较,结果令人满意。对超分子络合物电化学性质及分子识别机理进行了探讨。
In a buffer solution of 0.05 mol/L KCl(pH 6.95) ,the β-cyclodextrins-hexamethylenetetramine inclusion complex produces a reduction peak at potential of about -0.78 V (vs.SCE) on the 2.5th order differential liner sweep voltammetry curve. The peak is very stable. The peak current is linear with the concentration of hexamethylenetutramine from 4.0 × 10 to 1.0 ×10-2 mol/L, the detection limit is 1.5 × 10-4 mol/L. This
method has been applied to determine amounts of industrial product——hexamethylenetetramine and is contrasted
with conventional method with satisfactory results. The mechanism of the, molecular recognition and the characters of inclusion complex have also been studied .
