Determination of iron content 1,10-diazaphenanthrene spectrophotometry And inductively coupled plasma atomic emission spectrometry1 ScopeThis part of GB/T 13747 specifies the method for determination of iron content in zirconium and zirconium alloys. This section applies to the determination of iron content in sponge zirconium, zirconium and zirconium alloys. Measurement range. 0.010% ~ 0.40%. Method one for arbitration method. 2 Method 1. 1,10-diazaphenanthrene spectrophotometry 2.1 Principle The sample was decomposed with sulfuric acid-ammonium sulfate, zirconium was complexed with citric acid, and Fe3 was reduced to Fe2 with hydroxylamine hydrochloride. At around pH 6, Fe2 and 1,10-Diazaphenanthrene formed a red complex, and its absorbance was measured at a spectrophotometer wavelength of 510 nm. 2.2 Reagents Unless otherwise stated, only reagents and laboratory secondary water identified as analytically pure were used in the analysis. 2.2.1 Hydrochloric acid (1 1). 2.2.2 Ammonium sulfate. 2.2.3 sulfuric acid (ρ = 1.84g/mL). 2.2.4 Hydroxylamine hydrochloride solution (100g/L). 2.2.5 Citric acid solution (500g/L). 2.2.6 Acetic acid-ammonium acetate buffer solution. Weigh 500g of ammonium acetate to dissolve in water, add 20mL of glacial acetic acid, and dilute to 1000mL with water. Mix well. 2.2.7 Ammonia (1 1). 2.2.8 1,10-Diazaphenanthrene solution (5g/L). Weigh 0.5g of 1,10-diazaphenanthrene and dissolve it in 20mL absolute ethanol, and dilute with water to 100mL, mix well and store in brown bottle. 2.2.9 Iron standard storage solution. Weigh 1.000g of metallic iron (wFe≥99.99%), place it in a.200mL beaker, and add 30mL hydrochloric acid (2.2.1), heat to complete decomposition at low temperature, cool, transfer to 1000mL volumetric flask, dilute to the mark with water, and mix well. 1mL of this solution contains 1mg iron. 2.2.10 Iron Standard Solution. Transfer 10.00mL iron standard storage solution (2.2.9) into a 100mL volumetric flask, dilute to the mark with water, and mix uniform. 1 mL of this solution contained 100 μg of iron. 2.3 Instrument Spectrophotometer. 2.4 Sample The sample was processed into chips with a length of not more than 5 mm. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 13747.2-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 13747.2-2019_English as soon as possible, and keep you informed of the progress.
