前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件是GB/T11064《碳酸锂、单水氢氧化锂、氯化锂化学分析方法》的第1部分。GB/T11064已经

发布了以下部分：

—第1部分：碳酸锂含量的测定滴定法；

—第2部分：氢氧化锂含量的测定酸碱滴定法；

—第3部分：氯化锂量的测定电位滴定法；

—第4部分：钾量和钠量的测定火焰原子吸收光谱法；

—第5部分：钙量的测定火焰原子吸收光谱法；

—第6部分：镁量的测定火焰原子吸收光谱法；

—第7部分：铁量的测定邻二氮杂菲分光光度法；

—第8部分：硅量的测定钼蓝分光光度法；

—第9部分：硫酸根含量的测定硫酸钡浊度法；

—第10部分：氯量的测定氯化银浊度法；

—第11部分：酸不溶物量的测定重量法；

—第12部分：碳酸根量的测定酸碱滴定法；

—第13部分：铝量的测定铬天青S﹘溴化十六烷基吡啶分光光度法；

—第14部分：砷量的测定钼蓝分光光度法；

—第15部分：氟量的测定离子选择电极法；

—第16部分：钙、盐酸标准滴定溶液盐酸标准滴定溶液镁、铜、铅、锌、镍、锰、镉、铝、铁、

硫酸根含量的测定

电感耦合等离子体原子发射光谱法。

本文件代替GB/T11064.1—2013《碳酸锂、单水氢氧化锂、氯化锂化学分析方法第1部分：碳

酸锂量的测定酸碱滴定法》。与GB/T11064.1—2013相比，除结构调整和编辑性改动外，主要技术

变化如下：

a）更改了盐酸标准滴定溶液的浓度（见4.2.3，2013年版的3.2.1）；

b）更改了“称取质量”的相关内容（见4.5，2013年版的5.1）；

c）增加了“空白试验”的相关内容（见4.5.3）；

d）更改了“试验数据处理”的相关内容（见4.6，2013年版的第6章）；

e）删除了“允许差”的相关内容（见2013年版的7.2）；

f）增加了再现性条款（见4.7.2）；

g）增加了电位滴定法（见第5章）。
