%X 本文以核桃壳作为原料制备生物质炭，进行正交实验优化，考察了吸附温度、吸附时间、投加量、pH值以及吸附浓度对吸附性能的影响。结果表明：生物质炭对水中氨氮的最佳吸附条件为：吸附温度35℃，吸附时间45 min，生物质投加量0.1 g，吸附浓度100 mg/L，吸附pH值为7.0。该生物质的对氨氮吸附量为8.963 mg/g。<br />
This article used walnut shell as raw material to prepare biochar, and the orthogonal experiment was optimized to investigate the effects of temperature, dosage, pH value and concentration on adsorption performance. The results showed that the optimum adsorption conditions of biomass carbon for ammonia nitrogen in water were as follows: adsorption temperature 35℃, adsorption time 40 min, biomass dosage 0.1 g, adsorption concentration100 mg/L and adsorption pH 7.0. The ammonia nitrogen adsorption value of the biomass is 8.963 m g/g.
