摘要
研究了Zr(Ⅳ)-偶氮胂Ⅲ溶液的紫外吸收光谱。配制了两种不同类型的锆贮备溶液。发现对于相同锆浓度的溶液,高酸度的锆贮备溶液中的锆与偶氮胂Ⅲ形成的化合物的吸光度(λ=664nm)要大干仅由氧氯化锆配制的锆贮备溶液中的锆与偶氮胂Ⅲ形成的化合物的吸光度。
The UV-vis spectra of zirconium-zrsenazo Ⅲ solution were investigated. Two kinds of stocks solution of zirconium were prepared. With the same zirconium concentration, the absorbance of zirconyl oxyhalide solution （λ =664 nm） prepared in HCl was larger than that from pure zirconyl oxyhalide solution.
