研制了一种以7402-高铼酸盐为活性物质,对高铼酸根离子有选择性的PVC膜电极。电极对ReO_4~-离子选择性高,可用于测定含有大量MoO_4~(2-)、SO_4~(2-)、CO_3~(2-)、PO_4~()3-、Cl~-、ASO_4~(3-)等的溶液中的铼。
A kind of PVC membrane electrode with 7402-perrhenate as active material and with high rhenium ion selectivity was developed. The electrode has high selectivity to ReO_4 ~ - and can be used to determine the content of MoO_4 ~ (2 -), SO_4 ~ (2 -), CO_3 ~ (2 -), PO_4 ~ 3-) and the like solution of rhenium.
