New dinaphthosulfide podands [3(a, b, and c)] were synthesized. The structures of these compounds were confirmed by IR, 1H NMR, 13C NMR, and Mass spectra. A simple, efficient, and sensitive procedure is described for the spectrophotometric determination of a trace amount of Ag+, Hg2+, Cr3+, Pb2+, and Ni2+ cations in the presence of Mn2+, Co2+, Cd2+ cations using the podand (3a). Formation constants
合成了新的 dinaphthosulfide podands [3(a、b 和 c)]。这些化合物的结构通过IR、1H NMR、13C NMR和质谱证实。描述了一种使用 podand (3a) 在 Mn2+、Co2+、Cd2+ 阳离子存在下分光光度法测定痕量 Ag+、Hg2+、Cr3+、Pb2+ 和 Ni2+ 阳离子的简单、高效和灵敏的程序。1:1 复合物的形成常数由吸光度-摩尔比数据确定,发现其变化顺序为 Pb2+ > Ni2+ > Hg2+ > Cr3+ > Ag+。
