【摘要】 采用酸碱滴定法研究铜、铅、锌、铝离子与乙二醇的络合作用,并利用计算机软件MEDUSA模拟出它们的络合常数;试验结果表明乙二醇和铜、铅、锌离子之间的络合作用较弱,属物理作用范畴;而乙二醇和A l3+作用较铜、铅、锌离子为强,可生成一种新的沉淀物。更多还原

【Abstract】 The complexation of Cu2+,Pb2+,Zn2+,Al3+ with ethylene glycol was studied by potentiometric titration.MEDUSA,a computer software,was used to simulate the coordination constants of Cu2+,Pb2+,Zn2+,Al3+ with ethylene glycol,respectively.The results show that the reaction of Cu2+,Pb2+,Zn2+ with ethylene glycol was weak physical interaction,and the reaction of ethylene glycol with Al3+ was strong enough to form a new precipitate.更多还原
