中文摘要：

考察了以Mg-Al-LDHs为吸附剂脱硼过程中,各条件对产物脱硼效率的影响,考察的因素包括：吸附剂用量、硼溶液浓度、p H、吸附反应时间、温度、阴离子和阳离子杂质等。结果表明,吸附剂对硼的饱和吸附量为35 mg/g;90%硼的吸附发生在反应的前2 h内;Langmuir吸附等温式能较好地描述硼的吸附过程;p H在8-10的范围内,吸附量均较大。p H在小于8时,单位吸附量随p H的变化量很小;p H大于8时,随p H的增大,吸附量降低。将Mg-Al-LDHs吸附剂应用于海水淡化产品水的脱硼,脱硼率可达到85%。

英文摘要：

The performance of adsorbent Mg-Al-LDHs in the process of boron removal from desalted water was studied under different conditions.These conditions include the dosage of adsorbent, the concentration of boron solution, p H, reaction time of adsorption, temperature, anionic and cationic impurities. The result was that the saturated adsorption capacity of the adsorbent for boron was 35 mg/g; 90% of the boron adsorption occurred within the first two hours of the reaction; the adsorption process could be described by Langmuir adsorption isotherm; the adsorption quantity was large when p H ranged from 8 to 10; when p H was lower than 8, changing p H had little effect on the unit adsorption quantity; when p H was higher than 8, the adsorption quantity decreased with p H increasing. Mg-Al-LDHs could be applied in boron removal from desalted water and boron removal rate could reach 85%.
