it can be seen that WO3 is
stable in an acidic environment but will
dissolve in neutral and basic solutions.
The WO3 in the PA was removed using a pH 7
buffer solution (a mixture of sodium phosphate
and potassium phosphate with pH¼7.00 at 25 8C,
The VWR International) at room temperature.
查查无机化学书本,应该有这方面的反应介绍
可以,但产率不高

碱浸绝对可以
钨在水溶液中是以钨酸根存在的是阴离子,所以酸溶是不行的
三氧化物可以溶于氢氟酸,但是不溶于无机酸。可以查看 李洪桂教授编写的 稀有金属冶金学,前面有介绍。
