This part replaces the standards previously issued as. --- GB/T 4698.1-1984, GB/T 4698.1-1996. Sponge titanium, titanium and titanium alloys - Methods for chemical analysis Part 1. Determination of copper content Flame atomic absorption spectrometry1 ScopeGB/T 4698 provisions of this section sponge titanium, titanium and titanium alloys in the determination of the amount of. This section applies to the determination of copper in titanium sponge, titanium and titanium alloys. Measurement range .0.10% ~ 5.00%.2 method summaryThe sample was dissolved with hydrochloric acid and hydrofluoric acid. Nitric acid is added to oxidize titanium, and saturated boric acid is used to mask fluoride ions. Atomic Absorption Spectrometer wave 324.7nm long, the air - acetylene flame measured copper absorbance, according to the standard curve method of calculating the amount of copper.3 reagentUnless otherwise specified, only reagents that are identified as analytically pure and laboratory-grade water are used in the analysis. 3.1 hydrochloric acid (1 1). 3.2 Nitric acid (1 1). Hydrofluoric acid (1 1). 3.4 saturated boric acid solution. 3.5 copper standard stock solution Weigh 1.0000g metal copper (wCu ≥ 99.99%) placed in 300mL beaker, add 40mL nitric acid (3.2) slightly soluble. Boil, get rid of nitrogen oxides, remove the cooling, into 1000mL volumetric flask, add 50mL of nitric acid (3.2), with Dilute the water to the mark and mix well. This solution 1 mL contains 1.0 mg of copper. 3.6 copper standard solution Pipette 10.00mL copper standard stock solution (3.5) in 100mL volumetric flask, add 10mL of nitric acid (3.2), with Dilute the water to the mark and mix well. This solution 1mL containing 100μg copper.4 instrumentsAtomic absorption spectrometer with copper hollow cathode lamp. Under the instrument working conditions, any atomic absorption spectrometer that can achieve the following indexes can be used. --- Characteristic concentration. In the same solution with the sample solution of the matrix, the characteristic concentration of copper should not exceed 0.08μg/mL; --- Precision. With the highest concentration of standard solution measured 10 times the absorbance, the standard deviation should not exceed 1.0% of the average absorbance; The 10 absorbances measured with the lowest concentration standard solution (not the "zero" standard solution) should not exceed the standard deviation of the highest concentration Degree of standard solution 0.5% of the average absorbance; --- The working curve of the linear. The working curve according to the concentration is divided into five, the highest segment of the absorbance difference and the lowest segment of the absorbance difference Ratio, should not be less than 0.70.5 sampleSponge titanium, titanium and titanium alloy sampling should follow the standard methods have been promulgated. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 4698.1-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 4698.1-2017_English as soon as possible, and keep you informed of the progress.
