Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces GB/T 693-1996 "Chemical reagent sodium acetate trihydrate (sodium acetate)". Compared with GB/T 693-1996,
In addition to structural adjustments and editorial changes, the main technical changes are as follows.
--- Changed the technical requirements for clarity test from "qualified" to "≤ No. 2", "≤ No. 3" and "≤ No. 5" (see Chapter 5,.1996
Chapter 4 of the.2003 edition);
--- Added technical requirements for analytically pure and chemically pure potassium (see Chapter 5);
--- Added the determination method of copper and lead by flame atomic absorption spectrometry (see 6.10.1);
--- Added the determination method of potassium, calcium, copper and lead by inductively coupled plasma atomic emission spectrometry (see 6.10.2);
--- Deleted the determination method of anodic stripping voltammetry for copper and lead (see 5.12 and 5.13 of the.1996 edition);
--- Changed packaging and labeling (see Chapter 8, Chapter 7 of the.1996 edition).
