| 摘 要： | 研究了离聚物（MPET）粉末对Cr^3 的吸附性能，探讨了不同的吸附温度、时间、pH值和不同的初始浓度对吸附性能的影响，实验发现Cr^3 在较低温度下和pH为4时能被MPETO分末很好地吸附，最大饱和吸附量为11.80mg/g，实验表明MPET废纤维很可能发展成为一种经济的吸附重金属离子的材料。

| Abstract: | Modified polyethylene terephthalate (MPET) powder which contains sodium dimethyl 5-sulfodimethyl as the third comonomer component, was explored as an adsorbent for elimination of chromic ion in wastewater. The Ion was preferentially adsorbed at a lower temperature and pH4 onto MPET, the greatest saturation and adsorption capacity was 11.80mg/g. The experimental result showed that the MPET waste fiber may possibly be utilized as an economical adsorbent for heavy metal ions in wastewater. |
