摘要:
为促进大豆秸秆的资源化利用，以大豆秸秆为材料，采用慢速热解技术于400，500，600℃条件下制备生物炭吸附剂(BC400、BC500、BC600)，检测其去除废水中苯酚的效果。结果表明：生物炭的制备温度显著影响其对苯酚的吸附效果，3种温度制备的生物炭对苯酚的吸附能力表现为BC500>BC600>BC400。此外，废水中苯酚的初始浓度、吸附温度和时间等因素均能影响吸附效果。45℃下苯酚初始浓度为40 mg·L-1时，BC500对苯酚的去除率最高，达86%，生物炭对苯酚的等温吸附线符合Langmuir模式和Freundlich模型。研究结果探明了大豆秸秆制备生物炭吸附剂去除苯酚的最适条件，可为大豆秸秆应用于苯酚等有机污染物的去除提供理论依据。
Abstract:
The soybean straw was used as raw material to prepare the biochar adsorbent at 400, 500 and 600℃，which were named BC400，BC500 and BC600. Phenol was subject to batch adsorption in aqueous medium by the prepared soybean straw biochar. The results of adsorption experiments showed that the preparation temperature of biochar significantly affected its adsorption effect on phenol. The adsorption capacity of phenol from three kinds of biochar was BC500> BC600> BC400. In addition，the initial concentration of phenol in waste water, the temperature and time of adsorption could also affect the adsorption effect. When the initial concentration of phenol was 40 mg·L-1 and the adsorption temperature was 45℃，the removal rate of phenol was up to 86% treated by BC500. The isothermal adsorption line for phenol conforms to the Langmuir mode and the Freundlich mode. The results showed the best condition of phenol removal from aquous solution by soybean straw biochar, thus providing a theoretical basis for the removal of organic pollutants such as phenol.
