Embodiment 1
[0035] (1) Use a pipette to pipette 59.00±0.01 mL 0.2 mol·L -1 To 100 mL volumetric flask, then add 41.00±0.01 mL 0.2 mol·L -1 Acetic acid solution, vortex to mix evenly, make 100 mL pH=4.80±0.01 acetic acid-sodium acetate buffer solution.
[0036] (2) Weigh 8.70±0.01 g copper nitrate trihydrate and 6.75±0.01 g aluminum nitrate nonahydrate, mix them into a beaker, add 90±1 mL deionized water to the beaker, and stir with a magnetic stirrer for 10 min. Is completely dissolved, the prepared solution (c(Cu 2+ )=0.40 mol·L -1 , C(Al 3+ )=0.20 mol·L -1 ) Transfer to a 250 mL bottle infusion set for later use.
[0037] (3) Weigh 4.00±0.01 g of sodium hydroxide into a beaker, add a small amount of deionized water to the beaker, and stir with a magnetic stirrer for 10 minutes to dissolve it completely, and transfer the dissolved solution to a 100 mL volumetric flask , Made into 1.00mol·L -1 Sodium hydroxide aqueous solution, then transfer it to a 250 mL bottle infusion set for later use.
