This section compared with the GB/T 18570.2-2001, mainly for the following changes.
--- Increasing the range content;
--- In Chapter 4, the title "agent" to "Reagents and Materials" will be asked to test water listed separately, in Chapter 5 of the "pink
Pen, absorbent pad "Adjusting to Chapter 4, before filling Chinese name chemical formula, increases the computational concentration of mercury nitrate solution

--- Modify the provisions of the titration;
--- Will increase scrub time is 10min.
