| 摘 要： | 以改性球形纤维素吸附剂为载体,通过液相还原法,成功制取还原性球形纤维素吸附剂MSCB-Fe。Fe2+首先负载在改性纤维素吸附剂表面,接着被NaBH4溶液还原成零价铁。利用傅里叶变换红外光谱(FT-IR)、环境扫描电子显微镜(ESEM)、X射线衍射(XRD)和X射线能谱(EDAX)对MSCB-Fe进行表征,结果表明,液相还原法可成功在MSCB表面制取零价铁。并用MSCB-Fe进行氯仿的降解实验,氯仿的去除率高达84.4%。

| Abstract: | The modified spherical cellulose adsorbent （MSCB） was used as carrier for preparing reductive spherical cellulose adsorbent （MSCB-Fe）, by adopting aqueous reducing technique. Fe2＋ was first sorbed on the surface of MSCB, and then was reduced to Fe~ by NaBH4 solution. The MSCB-Fe was characterized by Fourier transform infrared spectroscopy （FT-IR）, environment scanning electron microscopy （ESEM）, X-ray diffraction （XRD） and energy dispersive X-ray analysis （EDAX）. The results demonstrated that Fe~ could be loaded on the MSCB successfully by aqueous reducing technique. In addition, MSCB-Fe was used for degrading chloroform, and the removal percentage of chloroform could reach 84.4%. |
