This standard replaces GB 22216-2008 Food additive—Hydrogen peroxide.
The following main changes have been made with respect to GB 22216-2008:
——The 30% product is deleted;
——The non-volatile and phosphate indexes of the 50% product are improved;
——The lead index of the 35% and 50% products is improved;
——The identification test is added;
——The limited visual colorimetry is deleted while the flame atomic absorption spectrometric method is added in the determination method of iron content;
——The test method of lead is modified to GB 5009.75;
——The arsenic spot method is deleted while the hydride atomic fluorescence spectrometry is added in the determination method of arsenic content.

Inspection methods
A.1 Warning
Chemicals such as hydrochloric acid, nitric acid, sulfuric acid and hydrogen peroxide samples used in the standard are corrosive and oxidizing, and users shall be careful to avoid splashing them on skin or eyes. In case of splashing to skin or eyes, rinse them immediately with water. In severe cases, seek medical treatment immediately.
A.2 General requirements
For the purpose of this standard, unless otherwise specified, all the reagents and water used refer to analytical reagents and Grade 3 water specified in GB/T 6682. Unless otherwise specified, the standard solution, standard solutions for impurity, preparations and products used in the tests shall be prepared in accordance with GB/T 601, GB/T 602 and GB/T 603. Unless otherwise specified, all solutions used in the test are aqueous solutions.
A.3 Identification test
A.3.1 Reagents and materials
A.3.1.1 Ether.
A.3.1.2 Sulfuric acid solution: 6 + 100.
A.3.1.3 Potassium dichromate solution: 75 g/L.
A.3.2 Identification method
Pipette 1 mL of specimen and place it in a tube with 1 drop of sulfuric acid solution and 10 mL of water. Shake well and add 2 mL of ether. Drop 1 drop of potassium dichromate solution, the water layer shall be blue temporarily, shake slightly and then stand still, and the ether layer shall be blue.
A.4 Determination of hydrogen peroxide (H2O2) content
A.4.1 Method summary
In acidic medium, oxidation-reduction reaction takes place between hydrogen peroxide reacts and potassium permanganate. The content of hydrogen peroxide is calculated according to the consumption of potassium permanganate standard titration solution.
A.4.2 Reagents and materials
A.4.2.1 Sulfuric acid solution: 1 + 15.
A.4.2.2 Potassium permanganate standard titration solution: c(1/5KMnO4) = 0.11 mol/L.
A.4.3 Analytical procedures
A.4.3.1 Weigh about 0.13g of 35% hydrogen peroxide specimen by the reduction method with 10 mL–25 mL dropping bottle, accurate it to 0.0002g, place it into a 250 mL conical flask filled with 100 mL of sulfuric acid solution.
A.4.3.2 Weigh 0.8g–1.0g of 50% hydrogen peroxide specimen by reduction method with 10 mL–25 mL dropping bottle, accurate it to 0.0002g, place it into a 250 mL volumetric flask, dilute it to scale with water, and shake well. Pipette 25 mL of the diluted solution into a 250 mL conical flask filled with 100 mL of sulfuric acid solution.
