This part replaces the standards previously issued as. --- GB/T 4698.4-1996; --- GB/T 4698.20-1996. Sponge titanium, titanium and titanium alloys - Methods for chemical analysis Part 4. Determination of manganese content Periodate spectrophotometry and Inductively coupled plasma atomic emission spectrometry1 ScopeGB/T 4698 provisions of this section sponge titanium, titanium and titanium in the determination of manganese content. This section applies to the determination of manganese in titanium sponge, titanium and titanium alloys. Determination of the range of 0.005% ~ 3.00%. The first method is arbitration Analysis method. 2 Method - a periodate spectrophotometry 2.1 Method summary The sample was dissolved with hydrofluoric acid and sulfuric acid. Titanium (IV) is oxidized from titanium in the low valence state to nitric acid, fluoride is complexed with boric acid, potassium iodate Manganese (Ⅱ) is oxidized to manganese (Ⅶ) and its absorbance is measured at a spectrophotometer wavelength of 525 nm. Coloring solution containing more than 1.0mg of chromium interference. A solution of sodium nitrite was added dropwise to discolor the permanganic acid and the solution was discolored Correction eliminates chromium interference. Other elements do not affect the determination. 2.2 Reagents Unless otherwise stated, only reagents identified as analytical grade and laboratory grade II water were used in the analysis. 2.2.1 boric acid. 2.2.2 potassium periodate. 2.2.3 Nitric acid (p = 1.42 g/mL). 2.2.4 hydrofluoric acid (1 1). 2.2.5 sulfuric acid (1 1). 2.2.6 sodium nitrite solution (20g/L), when used with the current. 2.2.7 Titanium metal (wTi ≧ 99.95%, wMn < 0.001%). 2.2.8 manganese standard storage solution Weigh 1.0000g beforehand washed with sulfuric acid (1 3) surface oxide and then washed with water and dried gold Manganese (wMn≥99.95%) in 100mL beaker, add 20mL sulfuric acid (2.2.5), dissolved by heating, cooling. Move into 1000mL capacity Bottle, diluted with water to the mark, mix well. 1 mL of this solution contains 1.0 mg of manganese. 2.2.9 manganese standard solution Pipette 50.00mL manganese standard stock solution (2.2.8) in 500mL volumetric flask, diluted with water to the mark, mixed uniform. 1 mL of this solution contains 100 μg manganese. 2.3 Instruments Spectrophotometer. 2.4 sample In accordance with the promulgated sponge titanium, titanium and titanium alloy take sample preparation standards. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 4698.4-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 4698.4-2017_English as soon as possible, and keep you informed of the progress.
