从酸性、中性或碱性溶液里, 微量高铼酸根都可以相当完全和高氯酸四苯基鉮共沉淀.在碱性溶液中, 用共沉淀法可使微量高铼酸根与大量钼酸根及其他阴离子分离.如果钼的含量特别大.再沉淀一次可使分离完全.将沉淀溶解於热水後加入高氯酸, 可使其中的高铼酸转入溶液, 并可直接进行比色测定.本文提出一种简单、迅速而易於控制的新方法以测定辉钼矿中的铼.精密度与准确度与蒸馏法、萃取法接近.

A new method for the separation of traces of rhenium by the method of coprecipitation has been proposed.It was successfully applied to the deterurination of rhenium in molybdenite, which compared well with the well-known distillation method and the extraction method in accuracy and precision.
