Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the Xiamen Marine Environment Monitoring Center Station of the State Oceanic Administration. This standard is under the jurisdiction of the National Marine Standardization Technical Committee (SAC/TC283). Drafting organizations of this standard. State Oceanic Administration Xiamen Marine Environmental Monitoring Center Station, State Oceanic Administration East China Sea Standard Metrology Center, National Oceanic Administration Environmental Monitoring Center, National Oceanic Information Center and School of Environmental Science and Engineering, Ocean University of China.

1 Scope

This standard specifies the use of atomic absorption spectrophotometry for the determination of iron, manganese, nickel, potassium, sodium, calcium, and magnesium in marine sediments and organisms. Digestion, analysis and measurement and data processing methods. This standard is applicable to the determination of iron, manganese, nickel, potassium, sodium, calcium, and magnesium in sediments and organisms in oceans, offshore, estuaries, harbors, etc.

3 Terms and definitions

The following terms and definitions apply to this standard. 3.1 Steam to dryness The solvent evaporates to a small volume (0.2mL~0.3mL), leaving a residue in a wet state. [GB 17378.6-2007, definition 3.1]

4 Principle

Marine sediment samples are digested by electric heating plate with nitric acid, perchloric acid and hydrofluoric acid or microwave digestion with mixed acids of nitric acid, hydrochloric acid and hydrofluoric acid; The samples of foreign organisms are digested by electric heating plate or microwave by nitric acid and hydrogen peroxide, iron is at a wavelength of 248.3nm, manganese is at a wavelength of 279.5nm, nickel At 232.0nm wavelength, potassium at 766.5nm wavelength, sodium at 589.0nm wavelength, calcium at 422.7nm wavelength, and magnesium at 285.2nm wavelength Measured by flame atomic absorption spectrophotometry; or manganese at 279.5nm wavelength, nickel at 232.0nm wavelength by flameless atomic absorption spectroscopy Photometric determination.

5 Reagents and preparation

Unless otherwise specified, superior grade pure reagents and double distilled water or equivalent pure water are used for analysis. 5.1 Nitric acid. 1.42g/mL, distilled by a quartz sub-boiling still. 5.2 Perchloric acid. 1.67g/mL. 5.3 Hydrofluoric acid. 1.49g/mL. 5.4 Hydrochloric acid. 1.19g/mL.
