This section GB/T 13747 part 15.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 13747.15-1992 "zirconium and zirconium alloys chemical analysis of curcumin spectrophotometric determination of boron." this
Part and GB/T 13747.15-1992 compared to editorial changes in addition to the main technical changes are as follows.
--- Measurement range from "0.00005% to 0.00025%" to "0.00005% to 0.00050%" (see Chapter 1,.1992 edition
Chapter 1);
--- Removed the "reference standard" (Chapter.1992 of Chapter 2);
--- The "separatory funnel extraction separation" was replaced by "G4 Funnel suction filtration" (see 6.4.5,.1992 version 6.3.5);
--- Increase the sample terms (see Chapter 5);
--- Will be allowed to change the precision of the terms (see Chapter 8,.1992 edition Chapter 8);
--- Added test report terms (see Chapter 9).

Methods for chemical analysis of zirconium and zirconium alloys
Part 15. Determination of boron content
Curcumin spectrophotometry
1 Scope
GB/T 13747 provisions of this part of zirconium and zirconium alloys Determination of boron content.
This section applies to sponge zirconium, zirconium and zirconium alloy determination of boron content. Determination range. 0.00005% ~ 0.00050%.
2 method summary
The sample was decomposed with ammonium sulfate-ammonium sulfate. In the sulfuric acid-glacial acetic acid medium, boron and curcumin generated Rose Bengal complex, and in dilute hydrochloric acid
Precipitate, dissolved in ethanol after separation. Absorbance was measured at a spectrophotometer wavelength of 550 nm.
3 reagent
Unless otherwise specified, only reagents that are identified as analytically pure and laboratory-grade water are used in the analysis.
3.1 Metal zirconium (wZr ≧ 99.95%, wB < 0.000001%).
3.2 Ammonium sulfate, excellent grade pure.
3.3 sulfuric acid. Measure.200mL sulfuric acid (ρ = 1.84g/mL, excellent grade pure) into platinum dish, add about 10mL of hydrofluoric acid (ρ = 1.15g/mL,
Excellent grade pure), stir with platinum wire, heated to take sulfuric acid smoke 30min, cooled and moved into the quartz bottle spare.
3.4 Glacial acetic acid (ρ = 1.05 g/mL).
3.5 anhydrous ethanol.
3.6 ether.
3.7 curcumin ethanol solution (1.25g/L). Weigh 0.50g of curcumin (C21H20O6), was dissolved in 400mL of absolute ethanol.
3.8 Hydrochloric acid (2 1).
3.9 Sodium hydroxide solution (100g/L). Prepared by premium pure sodium hydroxide.
3.10 Boron standard storage solution. Pre-boric acid (superior grade pure) dried at 105 ℃ 1h, cooled to room temperature, weighed 0.5711g placed
100mL beaker, add a small amount of water to dissolve slightly into the 1000mL volumetric flask, diluted with water to the mark, mix well. Store in plastic bottle
1 mL of this solution contains 100 [mu] g of boron.
3.11 Boron standard solution Pipette 5.00mL boron standard stock solution (3.10) in 1000mL volumetric flask, diluted with water to the mark, mixed
uniform. Stored in plastic bottles, this solution 1mL 0.5μg boron.
4 instruments
Spectrophotometer.
5 sample
5.1 Sampling
Sponge zirconium, zirconium and zirconium alloy sampling should be in accordance with the promulgation of the corresponding standard methods.
