摘要: 基于前期实验确定在氮气保护3种温度(550、650和750℃)制备秸秆黑碳,并用XRD、SEM对其结构、形貌进行了表征,研究它对吡唑酮废水中铵盐吸附去除效果。结果表明,650℃秸秆黑碳改变了晶体的有序度和结晶度,断面微孔道分布疏松均匀规则,具有较大的比表面积,而且有一定数量的纳米级黑碳颗粒;它的吸附特性优于750℃和550℃的秸秆黑碳,吸附率最高为95.31%;650℃秸秆黑碳最佳吸附工艺:吸附温度和饱和时间分别为35℃和4 h,吸附振荡频率为100 r/min。秸秆黑碳的吸附速率快、适用条件宽是处理铵盐废水的良好材料。

Abstract: On the basis of the previous experiment, black carbon was made from wheat straw with three different temperatures (550, 650, 750℃) under the nitrogen protection. Their particle sizes, structures, and morphologies were also tested by X-ray diffraction (XRD), and scanning electron microscopy (SEM), aiming to examine the effect of removing the ammonia nitrogen in pyrazolone wastewater. The experiments show that the sequence and crystallization degree of the crystal were changed by straw black carbon at 650℃. Micropore volume was distributed on the duct loosely, uniformly and regularly. Specific surface area was larger than the other. There was a certain number of nanoscale black carbon particles. The adsorptive characteristic of straw black at 650℃ was better than that at 750℃ and 550℃. The highest adsorption rate was 95.31%. The optimum conditions for absorptive power of straw black carbon at 650℃ are as the follows: the adsorptive temperature of 35℃; the adsorptive time of 4 h ; and the oscillation frequency of 100 r/min. With faster adsorption rate and wider applicability, straw black carbon at 650℃ is a good material to treat ammonia nitrogen wastewater.
