| 摘 要： | 利用HDTMA改性沸石制成吸附剂,研究对水体中硝酸盐的吸附能力和机理及吸附剂残渣的资源化应用前景。结果表明:HDTMA改性沸石可增强其对硝酸盐的吸附能力。通过红外光谱和差热分析它的吸附机理,表明:改性沸石HZ4吸附有十六烷基三甲基溴化铵(HDTMA)分子;吸附剂残渣NHZ4吸附有十六烷基三甲基溴化铵(HDTMA)分子和硝酸盐。盆栽实验结果表明:吸附剂残渣NHZ4能提高玉米生物量,最大增幅为30.4%。

| Abstract: | In this paper, the adsorbents of modified zeolite by Hexadecyl Trimethyl Ammonium Bromide （HDTMA） were used to study on the nitrate adsorptive capacity in water, adsorbing mechanism and the reclamation prospect of its residue. The results showed that the modified zeolite by HDTMA had high nitrate adsorptive capacity in water. The results of IR and DTA showed molecule frame for modified zeolite HZ4 and adsorbent residue NHZ4 had HDTMA, moreover, the latter had adsorbed nitrate. The adsorbent residue NHZ4 could promote maize growth and heighten its biomass to 30.4%. |
