摘要
等摩尔量递变法可以通过作图快速求算金属配合物的配位数n与配位稳定常数K,相对于常规的实验测定与复杂的后续求算方法,既保证了准确性,又简化了计算。实验方案中设计了吸光度校正,并进行体系pH控制确保定量配位,进一步减小实验测定和求算偏差,提高了实验结果的可靠性。
The coordination numbern and coordination stability constant K of metal complexes can be calculated quickly by equal-molar progressive method,offering a better accuracy and an easier calculation compared with the conventional experimental measurement and complex subsequent calculation method.Design on absorbance correction and pH control in the experiment reduced the deviation from experimental measurement and calculation,and improved the experimental reliability.
