前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T23276—2009《鈀化合物分析方法鈀量的測(cè)定二甲基乙二醛肟析出EDTA絡(luò)

合滴定法》。與GB/T23276—2009相比，除結(jié)構(gòu)調(diào)整和編輯性改動(dòng)外，主要技術(shù)變化如下：

a）更改了測(cè)定范圍的下限（見(jiàn)第1章，2009年版的第1章）；

b）更改了稱(chēng)樣量（見(jiàn)4.5.1，2009年版的6.1）；

c）更改了二甲基乙二醛肟析出EDTA絡(luò)合滴定法試樣的溶解及處理?xiàng)l件（見(jiàn)4.5.4，2009年版的

6.2）；

d）增加了再現(xiàn)性（見(jiàn)4.7.2）；

e）刪除了允許差（見(jiàn)2009年版的8.2）；

f）增加了二甲基乙二醛肟重量法（見(jiàn)第5章）。

請(qǐng)注意本文件的某些內(nèi)容可能涉及專(zhuān)利。本文件的發(fā)布機(jī)構(gòu)不承擔(dān)識(shí)別專(zhuān)利的責(zé)任。
