[Identification] Take 0.1g of this product, disperse it in 20ml of water, add 0.4ml of 10% sodium hydrochloride solution to form a gel.

【an examination】
Acidity Take 0.10g of this product, evenly disperse and swell it in 10ml water, check according to law, the pH value should be 2.5~3.5.
Viscosity: Take 0.5g of this product and disperse it evenly in 98ml of water. After it is fully swelled, mix well, adjust the pH to 7.3~7.8 with 15% sodium hydroxide solution (test with precision pH test paper), add water to 100ml, and mix ( Avoid air bubbles), measured according to the law (Appendix VIG Method 2), the dynamic viscosity at 25℃ should be 15~30Pa•s.
Benzene: Take about 1g of this product, accurately weigh it, place it in a test tube with a stopper, add 10.0ml p-xylene, shake to disperse the product, add 10.0ml of 0.1mol/L sodium hydroxide solution, and shake it tightly for 1 hour. Take the supernatant as the test solution. Take an appropriate amount of benzene, accurately weigh it, and add p-xylene to make a solution of 10 µg per 1 ml as a reference solution. Precisely measure 1µl each of the test solution and the reference solution, and determine according to gas chromatography (Appendix ⅤE), using a 3m glass column, the support is 201 red support (60-80 mesh), and dinonyl phthalate Mixed with the same amount of organic bentonite as a fixing solution, the coating concentration is 10%, and the column temperature is measured at 100°C. Benzene must not exceed 0.01%.
Loss on drying Take this product and dry it under reduced pressure at 80°C for 1 hour. The weight loss should not exceed 2.0%.
Residue on ignition Take 1.0g of this product and inspect according to law. The remaining residue shall not exceed 2.0%.
Heavy metals Take the residues left over under the item of residues on ignition, and inspect them in accordance with the law. The content of heavy metals shall not exceed 20 parts per million.

[Content determination] Take about 0.4g of this product, accurately weigh it, and disperse it evenly in 400ml of water, stir to dissolve it, and titrate with sodium hydroxide titrant (0. 25mol/L) according to the potentiometric titration method (Appendix VIIA) (near At the end, stir for at least 2 minutes after each drop). Each 1ml of sodium hydroxide titrant (0.25mol/L) is equivalent to 11.25mg of -COOH.
