The thermal decomposition reaction of Eu2(p-MBA)6(PHEN)2 (p-MBA=CH3C6H4COO, methylbenzoate;PHEN=C12H8N2, 1,10-phenanthroline) was studied in a static atmosphere
A simple and sensitive method for the determination of trace amount of yttrium by solid-phase spectrophotometry has been studied. Yttrium can form a 1∶1 comple
The variation of microstucture and phase structure of metal Cr and Al powders prepared by high energy mechanical milling was analyzed and investigated.The resul
The surface coating of grinding balls was investigated experimentally. The results show that a coating may form on the surface of grinding balls when Cr or Al p
A new selective and sensitive kinetic method for determination of trace amounts of vanadium(Ⅴ) (0.5~40ng/ml) based on its catalytic effect on the oxidation of a
