摘要：

A simple and rapid method for extractive separation of vanadium(V), niobium(V), and tantalum(V) from halide media has been worked out using triphenylphosphine oxide in toluene as an extractant. The optimum conditions for extraction and. separation have been evaluated from critical study of various variable factors. The log-log plots are used to ascertain probable extractable species. The method is applicable to the analysis of standard alloy samples and synthetic mixtures. The results are reproducible and accurate.
