| 摘 要： | 降低海水镁砂中硼的含量有许多方法,例如碱洗法、过碱法、吸附法和选择性吸硼树脂法等。我们先采用吸附法制得低硼海水(含B_2O_33ppm),再用改良过碱法进一步降低硼含量,可制得含B_2O_3为0.01—0.02%的低硼海水镁砂。比较结果,联合法降硼比单一法降硼优越。 用Mg(OH)_2作吸附剂,吸硼后变为含硼沉淀,经过碱洗脱硼后,可循环使用。

PREPARATION OF MAGNESIA BY REDUCING ITS BORON CONTENT WITH COMBINATION METHOD |
| |
| Abstract: | One of the following methods: alkali-washing method, overlime method, adsorption method and selected removing boron resin etc. was used to decrease the content of boron oxide in sea-water magnesia. We first prepared low boron content sea water with adsorption method, then with the improved overlime method to reduce the boron content, and obtained low boron content sea-water magnesia (as B2O3: 0.01 - 0.02%). The combination method of reducing boron content is superior to any single method. Mg(OH)2 was used as adsorbent. It must be washed with alkali soln after adsorbing a store of boron from sea water. After the alkaliwashing, Mg(OH)2 was circulated as adsorbenyagain. |
