A method is described for the separation of titanium, zirconium, iron, and aluminum from one another and for their subsequent determination. Iron is first precipitated with 1-nitroso-2-naphthol after complexing the titanium and zirconium with citrate to prevent their precipitation. Titanium and zirconium are then collectively precipitated with cupferron and subsequently separated from each other by precipitating the titanium with 8-hydroxyquinoline after complexing the zirconium with ethylenediaminetetraacetic acid. Aluminum and zirconium are recovered from their respective solutions by precipitation with cupferron. The accuracy of the method was proved by analyzing synthetic solutions containing known amounts of the four elements.
本文描述了一种将钛、锆、铁和铝彼此分离并随后进行测定的方法。首先，在用柠檬酸盐络合钛和锆以防止它们沉淀之后，用1-亚硝基-2-萘酚沉淀铁。然后，用铜铁灵将钛和锆共同沉淀，随后在用乙二胺四乙酸络合锆之后，用8-羟基喹啉沉淀钛，从而将它们彼此分离。通过用铜铁灵沉淀，从各自的溶液中回收铝和锆。通过分析含有已知量这四种元素的合成溶液，证明了该方法的准确性。
