ICP-AES法测定球形氢氧化亚镍中的主成分及杂质

Determination of main contents and impurities of sphere nickel hydroxide by ICP-AES

采用ICP-AES法测定球形氢氧化亚镍中主成分锌、镉、钴及杂质钙、镁、锰、铜、铁、铅、硅、银等11种元素,并对镍基体对被测元素的干扰,以及酸度的影响进行了研究.该方法的回收率为90%～104%,相对标准偏差为0.74%～5.9%.目前,该方法已应用于生产中,结果较满意.

Determination of main contents such as Zn,Ge and Co and impurities such as Ca,Mg,Mn,Cu,Fe,Pb,Si and Ag in sphere nickel hydroxide were realiz ed by inductive coupled plasma optical emission spectrometry (ICP-AES). Recover y of the method was between 90%～104%,and RSD was between 0.74%～15%. At pr esent, this method has been applied in production and the result is satisfactory .
