Zheng Rui Yang Lin, Zhang Yan. Tooth bleaching material Determination of content of peroxides1 ScopeThis standard specifies the tooth bleaching materials and other products have teeth bleaching effect of peroxide (hydrogen peroxide, urea peroxide) containing Determination of the amount. This standard applies to tooth bleaching materials and other products have teeth bleaching effect of peroxide (hydrogen peroxide, urea peroxide) containing Determination of the amount. Method 2 2.1 Equipment 2.1.1 electronic balance (0.0001g). 2.1.2 magnetic stirrer and stirrer. 2.1.3 oven (± 1 ℃). 2.2 Reagents 2.2.1 Glacial acetic acid, analytical grade. 2.2.2 Potassium iodide, analytical grade. 2.2.3 paramolybdate (TS), 10% (mass fraction). 2.2.4 sodium thiosulfate standard solution, 0.1mol/L. 2.2.5 starch, 0.5% (mass fraction). Step 2.3 2.3.1.1 preparation Weigh 26g of sodium thiosulfate (Na2S2O3 · 5H2O) or 16g anhydrous sodium thiosulfate (Na2S2O3)], was dissolved in 1000mL water Was slowly boil, kept 10min, cool. Filter to be calibrated for two weeks. 2.3.1.2 Calibration Said learn 120 ℃ drying to constant weight, baseline potassium dichromate 0.15g (accurate to 0.0001g), placed in 500mL iodine bottle. Join 25mL of deionized water and dissolved, then add 2g of potassium iodide and 20mL20% sulfuric acid solution, shake, in the dark place 10min. plus 150mL deionized water into the bottle wall and bottle, with the 2.3.1.1 sodium thiosulfate solution titrated formulated 0.1mol/L of. near 3mL of starch indicator was added (5g/L) when the end point, and continue titration until the solution turns from blue to green. While doing the blank test. Calibration Good The solution was placed in a cool place, more than three months to be re-calibrated. 2.3.1.3 Calculation (1) Where. Ba (Na2S2O3) --- concentration of sodium thiosulfate standard solution, unit mole per liter (mol/L); Vp 1 --- the amount of sodium thiosulfate standard solution, in milliliters (mL); ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YY/T 0632-2008_English be delivered?Answer: Upon your order, we will start to translate YY/T 0632-2008_English as soon as possible, and keep you informed of the progress.
