This part replaces the standards previously issued as. --- GB/T 4698.13-1984, GB/T 4698.13-1996. Sponge titanium, titanium and titanium alloys - Methods for chemical analysis Part 13. Determination of zirconium content EDTA complexometric titration and inductive coupling Plasma atomic emission spectrometry1 ScopeGB/T 4698 provisions of this section sponge titanium, titanium and titanium alloy zirconium content determination. This section applies to the determination of titanium sponge titanium, titanium and titanium alloy, the method of a determination of the range of 0.50% ~ 15.00%, Method 2 Determination Range .0.010% ~ 15.00%. Method two is the method of arbitration analysis.2 Method One EDTA complexometric titration2.1 Method summary The sample is dissolved with hydrochloric acid, hydroxylamine hydrochloride is added to eliminate the interference of iron and other coexisting elements, and the mixture is heated under hydrochloric acid medium to dimethyl Phenol orange as an indicator, with EDTA standard titration solution titration of zirconium. Niobium coexist titration end of the phenomenon back to the phenomenon should be repeated heating titration end of the color constant. 2.2 Reagents Unless otherwise specified, only reagents that are identified as analytically pure and laboratory-grade water are used in the analysis. 2.2.1 Hydrogen peroxide (p = 1.10 g/mL). 2.2.2 Hydrochloric acid (1 1). 2.2.3 hydroxylamine hydrochloride solution (100g/L). 2.2.4 zirconium standard solution (1mg/mL). 2.2.4.1 Preparation Weigh 3.533g zirconyl chloride (ZrOCl2 · 8H2O) in 500mL beaker, add 100mL hydrochloric acid (2.2.2) so that Dissolved into 1000mL volumetric flask, diluted with water to the mark, mix well. 2.2.4.2 Calibration. Pipette three 25.00 mL portions of zirconium standard solution (2.2.4.1) into three 250 mL beakers, dilute with water to about 100mL, add 1g of ammonium chloride, heated to 70 ° C, ammonia solution was added dropwise under stirring (11) to ammonia smell, heated to boil, remove and place 30min. Filtered on medium speed quantitative filter paper and the precipitate was washed 4 times with ammonium nitrate solution (20 g/L) and twice with water. Will precipitate and filter paper Into a constant weight platinum crucible, drying, ashing, burning in a high temperature furnace at 1000 ℃ to constant weight. According to equation (1) calculate the concentration of zirconium standard solution (2.2.4.1). c1 = (m2-m1) × 1000 × 0.7403 V1 (1) In the formula. c1 --- zirconium standard solution (2.2.4) of the actual concentration in milligrams per milliliter (mg/mL); m2 --- zirconium dioxide and platinum crucible mass, in grams (g); m1 --- platinum crucible mass in grams (g); V1 --- Remove the volume of zirconium standard solution (2.2.4.1), in milliliters (mL); 0.7403 --- Zirconium dioxide conversion factor for zirconium. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 4698.13-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 4698.13-2017_English as soon as possible, and keep you informed of the progress.
