【摘要】 合成了两种铁氧化物———针铁矿、赤铁矿,用红外光谱、X-晶体衍射及BET等手段对铁氧化物进行了表征,并研究了铁氧化物吸附苄嘧磺隆的特性。研究结果表明,针铁矿和赤铁矿是纯度较高的氧化物,针铁矿吸附苄嘧磺隆的量大于赤铁矿。更多还原

【Abstract】 Two oxides goethite and hematite were prepared.The oxides were characterized through modern techniques of XRD,FTIR,and the particle characteristics were tested with BET method.Moreover,the study on adsorption to bensulfuron-methyl（BSM） was carried out with batch equilibration technique.The results showed the two iron oxides were α-FeOOH and α-Fe₂O₃, respectively.Within the range of BSM concentration used in the experiment,the amount of BSM adsorption increased with the concentration of BSM increasing,and the adsorption ability of goethite to BSM was stronger than that of hematite.更多还原
