GB/T 31981 Titanium and titanium alloy chemical composition analysis sample preparation method3 samples3.1 Sampling Sampling of titanium sponge, titanium and titanium alloy shall be carried out in accordance with GB/T 31981. 3.2 Sample processing The sample was cut into pieces having a length of not more than 5 mm. 4 Method 1. methine blue spectrophotometry 4.1 Principle The sample was dissolved with hydrofluoric acid, and hydrogen peroxide was used to oxidize titanium. Boron and hydrofluoric acid form fluoroborate complex ions in an acidic solution, followed by methine Blue formed a green complex, which was extracted with 1,2-dichloroethane, and its absorbance was measured at a wavelength of 660 nm of a spectrophotometer. 4.2 Reagents Only analytically pure reagents and laboratory secondary water were used in the analysis unless otherwise stated. 4.2.1 Metal titanium (wTi ≥ 99.9%, wB < 0.0002%). 4.2.2 1,2-Dichloroethane. 4.2.3 Hydrogen peroxide (ρ = 1.10 g/mL). 4.2.4 Hydrofluoric acid (5 3). Stored in a polyethylene bottle. 4.2.5 Sulfuric acid..200mL sulfuric acid (ρ=1.84g/mL, excellent grade pure) was injected into the platinum dish, and 10mL hydrofluoric acid (ρ=1.15g/mL) was added. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 4698.6-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 4698.6-2019_English as soon as possible, and keep you informed of the progress.
