高速分析法测定球形Ni(OH)_2中SO_4^(2-)

Determine SO_4^(2-) in spherical Ni(OH)_2 by high speed analyze method

球形Ni(OH) 2 中硫酸根是主要杂质 ,目前常采用的方法是比浊法和质量法 ,存在不同程度的遗憾。采用高速分析法测定球形Ni(OH) 2 中SO2 -4 ,经试验和生产应用证明 ,具有快速、准确、定量的特点 ,适用于球形Ni(OH) 2 生产控制指标及电池生产企业质检分析 ,分析一个样品仅需 3～ 5min ,是目前球形Ni(OH ) 2 分析最快的方法。检测下限精确到10 -4 。

Sulfate radical was main impurity in spherical Ni(OH) 2, and now high speed analyze method was used to determine SO 2- 4 in spherical Ni(OH) 2. The results show that the method is suitable to be used in manufacture control target for nickel and in quality test for battery manufacturer. The method is the quickest analyze method for spherical Ni(OH) 2. To analyze a sample only need 3～5 min, and the test lower limit is accurate to 10 -4 .
