Foreword
This standard and ISO 6353-1. 1982 "Chemical analysis of reagent --- Part 1. General test method" non-equivalent.
This standard replaces GB/T 610.1-1988 "Chemicals general method determination of arsenic (arsenic spot method)" and GB/T 610.2-1988 "of
General method for determination of arsenic chemical reagent (diethyl dithiocarbamate silver law) ", and GB/T 610.1-1988, GB/T 610.2-1988
Compared to the main changes are as follows.
--- Increase Gutzeit method for the determination of the scope (Chapter 1 of this edition);
--- Clear Gutzeit method to limit law, diethyl dithiocarbamate silver method for the quantitative method (Excerpts 4.1.1,4.2.1);
--- Canceled GB/T 610.2 Appendix A (1988 edition of Appendix A).
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standardization Technical Committee Chemistry Chemicals Branch (SAC/TC63/SC3) centralized.
This standard was drafted. Shanghai Institute of chemical reagents.
The main drafters of this standard. Suiqi Ying, Sheng Xiaohua.
This standard replaces the standards previously issued as follows.
--- GB/T 610-1965, GB/T 610-1977, GB/T 610.1-1988;
--- GB/T 610-1965, GB/T 610-1977, GB/T 610.2-1988.
General method for determination of arsenic chemical reagents
1 Scope
This standard applies to the determination of trace amounts of arsenic. Gutzeit method suitable for measuring the arsenic content in 1μg ~ 5μg (As) within the scope of the test solution.
Diethyl dithiocarbamate silver method (AgDDTC) detection range in the absorbing liquid was 0.1μg/mL ~ 4μg/mL (As).

3 Reagents
Unless otherwise specified in this standard, all standard solution, preparations and products, according to GB/T 602, the provisions of the preparation of GB/T 603, the experiment
Water should be consistent with GB/T 6682 in two water specifications.
4 Determination
4.1 Gutzeit method
4.1.1 The principle of the method
In acidic solution, potassium iodide and stannous chloride As (Ⅴ) reduced to As (Ⅲ), plus zinc particles react with acids to produce nascent hydrogen to
As (Ⅲ) is further reduced to arsine. Arsine gas when the mercury bromide paper effect and will vary depending on the amount of arsenic produce different shades of brown
Yellow mercury arsenic compounds, arsenic can be used to limit visual colorimetric assay.
4.1.2 Instruments
4.1.2.1 general laboratory equipment.
4.1.2.2 arsenic given device
Arsenic given apparatus shown in Fig. Measured before the mercury bromide paper sandwiched between glass and glass upper nozzle cap with a rubber band or other parties
The upper end of the glass cap method and the glass tube spout fixed.
