First, a mixture solution of 0.09 M FeCl3 and 0.01 M MgCl2 was obtained by dissolving proper amounts of FeCl3 and MgCl2 into 70 mL ethanol. Then, 10 mL NaOH ethanol solution (2.03 M) was added into the mixture solution to obtain the fixed molar ratio of NaOH:FeCl3 of 3:1 and NaOH:MgCl2 of 2:1 at room temperature, and the reaction lasted for 1 h under ultrasonic oscillation.
首先,将适量的 FeCl3 和 MgCl2溶于70ml乙醇中,得到0.09MFeCl3 and 0.01 M MgCl2混合液。然后,将 10 mL (2.03 M) NaOH乙醇液加到混合液中,以使(混合分子比)NaOH:FeCl3为3:1,NaOH:MgCl2为 2:1;反应在室温,超声波振动下进行1小时。 |
