Polyacrylamide, pam, determination of ionicity

(Summary description)Solution preparation 0.1mol/L hydrochloric acid solution, 0.1% methyl orange solution, stored in a brown glass bottle, 0.25% indigo sodium disulfonate solution, stored in a rafter-colored dropper bottle The preparation of polymer solution: 1) Weigh a sample of 0.028~0.0329 composite ion polyacrylamide, accurate to ±0.00019. 2) Place an Erlenmeyer flask containing 100ml of distilled water on the electromagnetic stirrer, make the water swirl, and slowly add the sample into the Erlenmeyer flask. 3) After the sample is completely dissolved, the degree of hydrolysis can be directly measured. 4) Add one drop of methyl orange and one drop of indigo sodium disulfonate indicator to it. The sample solution is yellow-green. Titrate the sample solution with a hydrochloric acid standard solution. The yellow-green color of the solution turns to light gray as the end point of the titration. Note the consumption Hydrochloric acid standard The number of milliliters of the quasi-solution. Calculate the degree of hydrolysis: HD=CV×71×1000 ∕ 1000m×s-23cv In the formula: HD-degree of hydrolysis% R~Concentration of hydrochloric acid standard solution mol/L V The number of milliliters of the standard solution of holmonic acid consumed in m1 M-the mass of the powder sample g R-Solid content of powder sample%
