thorium nitrate

Methods The samples of phytic acid were determined with thorium nitrate titration, ferric spectrophotometry, phosphorus spectrophotometry and high performance liquid chromatography respectively.

方法用硝酸钍滴定法、测铁分光光度法、测磷分光光度法及高压液相色谱法对不同样品植酸含量进行测定。

Reported herein are eight solid complex compounds obtained by reactions of uranyl nitrate, uranyl chloride and thorium nitrate with macro-cyclic polyethers dibenzo-18-crown-6, benzo-15-crown-5 and 18-crown-6 in polar solvents. The complex compounds have been characterized by elemental analysis, melting points and infrared spectro-metric analysis.
