This section applies to the determination of silicate rocks in the amount of aluminum oxide, aluminum oxide also applies to the amount of soil and stream sediments in Determination. Measurement range. 3% to 20% of the amount of aluminum oxide.2 Normative referencesThe following documents contain provisions which, through reference GB/T 14506 in this section constitute provisions of this section. For dated reference documents Member, all subsequent amendments (not including errata content) or revisions do not apply to this section, however, encouraged to reach under this section Parties to research agreement to use the latest versions of these documents. For undated reference documents, the latest versions apply to this section. Laboratory use specifications and test methods GB/T 6682 Analysis GB/T 14506.1 Silicate rocks - Part 1. Determination of water adsorption Principle 3 Sample with sodium carbonate melt, the filtrate was measured after separating the silica or with hydrofluoric acid, sulfuric acid, potassium pyrophosphate fusion Preparation of the solution was measured. In hydrochloric acid medium, so that with the addition of excess EDTA iron, aluminum, titanium and other complex, adjusted to pH6, semi-xylenol orange as Indicator, with zinc standard solution titration of excess EDTA, followed by addition of potassium fluoride substituted with aluminum, titanium complexed EDTA, zinc and then mark Standard solution titration released EDTA, this is aluminum, titanium alloy amount that was subtracted from the amount of titanium aluminum content.4 ReagentsUnless otherwise stated in this section are consistent with the use of analytical reagent and GB/T 6682 analytical laboratory use in the analysis. 4.1 potassium pyrosulfate. 4.2 Hydrofluoric acid (ρ1.15g/mL). Warning --- toxic and corrosive hydrofluoric acid, the operation should wear gloves to prevent skin contact. 4.3 ethanol. 4.4 sulfate (11). Warning --- improper dilution risk prone 4.5 Glacial acetic acid (ρ1.05g/mL). 4.6 acetic acid (11). 4.7 hydrochloride (11). 4.8 hydrochloride (19). 4.9 Aqueous ammonia (11). 4.10 zinc acetate solution (50g/L). 4.11 sodium fluoride solution (200g/L). Stored in plastic bottles. 4.12 acetic acid - sodium acetate buffer solution (pH5.7). Weigh 200g of sodium acetate (NaAc · 3H2O) were dissolved in water and glacial acetic acid added 6mL ...... |
