取代基对二苯并冠醚与Pb^(2+)和Cd^(2+)络合容量的影响

The Effect of Substituted Groups on Complexing Capacity of Dibenzo-crown Ethers with Pb^(2+) and Cd^(2+)

本文利用原子吸收分光光度法,测定了8种取代酰基二苯并-24-冠-8对Pb^(2+)和Cd^(2+)的络合容量。并讨论了不同取代基对二苯并-24-冠-8与Pb^(2+)和Cd^(2+)络合容量的影响。

The complexing capacity of eight kinds of crown ethers with Pb^(2+)and Cd^(2+)is determined by atomic absorption spectrophometry.The effect of substituted groups on complexing capacity of dibenzo-crown ethers with Pb^(2+)and Cd^(2+)is discussed.
