摘要：通过 K氏蒸馏法测定尿素高温水解合成 α- Ni(OH) 2 结构中嵌入氨的含量。探讨了吸收装置、样品溶解、Na OH溶液加入方式和蒸馏时间等因素对测定结果的影响。在最佳实验条件下 ,测得α- Ni(OH) 2 结构中氨的含量为 3.6 1 % (质量分数 )。
Intercalated NH 3 in α Ni(OH) 2 which was synthesized by hydrolysis of urea, was measured by Microkjeldahl procedure. The effects of absorbing apparatus, dissolving sample, mode of feeding NaOH and distilling time on accuracy were studied. The results showed that the sample should be absolutely dissolved, NaOH solution was fed slowly and distilling time was 20 min, the contents of the intercalated NH 3 in α Ni(OH) 2 were 3.61%( m/m ).
