亚铊和硫氰酸根的络合反应已有不少研究但结果分歧较大(参阅表1)。其原因大致有:(1)有些实验配位体浓度不够大;(2)有些突验未使溶液的离子强度恒定。有的实验用硝酸钠维持离子强度而忽略了亚铊与硝酸根间的络合反应。Davis和 Nair 等分别用电导法和溶度法证明硝酸亚铊 There have been many studies on the complexation of thallium and thiocyanate but the results are highly divergent (see Table 1). The reasons are as follows: (1) some experimental ligand concentration is not big enough; (2) some test did not make the ionic strength of the solution constant. Some experiments with sodium nitrate to maintain ionic strength and ignore the complex reaction between thallium and nitrate. Davis and Nair et al. Used conductivity and solubility methods to demonstrate thallium nitrate
