1 Scope

This standard specifies seawater cooling water inductively coupled plasma emission spectrometry (ICP-AES), flame atomic absorption spectrophotometry and Phenanthroline spectrophotometric method for the determination of three kinds of iron. This standard applies to the determination of total iron and soluble iron content in seawater cooling water. Inductively coupled plasma emission spectroscopy (ICP-AES) is the arbitration method, the lower limit of detection is 0.02mg/L; the lower limit of detection of flame atomic absorption spectrophotometry is 0.20mg/L; adjacent The detection limit of phenanthroline spectrophotometry is 2μg.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Totaliron Suspended matter in seawater is the sum of adsorbed iron, dissolved iron, colloidal iron and iron in microorganisms. 3.2 Soluble iron The sum of all forms of iron present in seawater after filtration through a 0.45μm filter membrane. 4 Inductively coupled plasma emission spectrometry (ICP-AES) 4.1 Principle of the method The liquid sample forms an aerosol through the atomizer, enters the ICP source maintained by plasma argon, and dissociates almost completely at high temperatures, and the atoms The electrons in the middle and outer layers emit characteristic spectral lines when the excited state transitions to the ground state, and reach the detector through the optical system. This standard uses 259.9nm The spectral line of the wavelength. 4.2 Reagents and materials 4.2.1 Reagents and water In the analysis method, except for special regulations, all superior grade pure reagents and first-level water or second-level water in accordance with GB/T 6682 are used. 4.2.2 Nitric acid ......
