Determination of aluminum content Method 1 a Chromium Azure S Spectrophotometry 1.1 Scope This method specifies the method for determination of copper and copper alloy aluminum content. This method is applicable to the determination of copper and copper alloy aluminum content. Measurement range. 0.0010% to 0.50%. 1.2 Principle of the method The sample is dissolved in nitric acid, an acid precipitation tin biased filter, electrically released copper. Partial recovery treatment with hydrobromic acid adsorption of trace aluminum tin. Phosphorous Mass fraction is large, and extracted with ethyl aluminum - benzoyl phenylhydroxylamine complex with phosphorus separation, and then the same aluminum back-extracted water main were combined and. Interference to lift a lot of lead in the copper electrical power before releasing lead. Hydrofluoric acid to remove the volatile silicon is high. Perchloric acid solution of hydrochloric acid in addition to chromium to smoke Eliminate its effects. Interference with beryllium disodium edetate as masking agents beryllium hydroxide precipitate was separated and removed with acid masking bitter almond titanium. Zinc, Effect of addition of nickel equivalent amount of zinc and nickel in the blank test to offset with ascorbic acid and thiourea eliminate the influence of iron and residual copper. Copper Alloy Other elements present in the non-interference. About pH6, chromium azure S color, measured at 545nm wavelength spectrophotometer its absorption Luminosity. 1.3 Reagents Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity. 1.3.1 pure zinc (mass fraction of aluminum < 0.001%). 1.3.2 ethyl acetate. 1.3.3 Extraction solvent. unit volume of 4-methyl-2 - pentanone -2 toluene was mixed with 1 volume unit. 1.3.4 perchloric acid (ρ1.67g/mL) pure class distinctions. 1.3.5 hydrobromide (ρ1.49g/mL) pure class distinctions. 1.3.6 Hydrofluoric acid (ρ1.13g/mL) pure class distinctions. 1.3.7 hydrochloric acid (ρ1.18g/mL) pure class distinctions. 1.3.8 nitrate (ρ1.42g/mL) pure class distinctions. 1.3.9 nitric acid (1 + 1) pure class distinctions. 1.3.10 nitrate (98 + 2). 1.3.11 nitric acid (1 + 99). 1.3.12 hydrochloric acid (1 + 1) pure class distinctions. 1.3.13 hydrochloric acid (1 + 39). 1.3.14 hydrochloride [Ba (HCl) = 0.2mol/L]. 1.3.15 hydrochloride [Ba (HCl) = 0.1mol/L]. 1.3.16 ammonia (1 + 1) pure class distinctions. 1.3.17 ammonia (1 + 2) pure class distinctions. 1.3.18 ammonia water (1 + 9) pure class distinctions. 1.3.19 sulfuric acid (1 + 1) pure class distinctions. 1.3.20 nickel solution (5g/L). Weigh 1.000g of pure nickel (aluminum content of < 0.0005%), was added 15mL of nitric acid (1.3.9), plus Heat to dissolve, boiled to remove nitrogen oxides, cooling. Transferred to 200mL volumetric flask, dilute with water to volume, and mix. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 5121.13-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 5121.13-2008_English as soon as possible, and keep you informed of the progress.
