Abstract

Magnetic polyvinyl alcohol adsorbent M-PVAL was employed to remove and concentrate dimethyl phthalate DMP. The M-PVAL was prepared after sequential syntheses of magnetic Fe3O4 (M) and polyvinyl acetate (M-PVAC). The saturated magnetizations of M, M-PVAC, and M-PVAL are 57.2, 26.0, and 43.2 emu g(-1) with superparamagnetism, respectively. The average size of M-PVAL by number is 0.75 μm in micro size. Adsorption experiments include three cases: (1) adjustment of initial pH (pH0) of solution to 5, (2) no adjustment of pH0 with value in 6.04-6.64, and (3) adjusted pH0 = 7. The corresponding saturated amounts of adsorption of unimolecular layer of Langmuir isotherm are 4.01, 5.21, and 4.22 mg g(-1), respectively. Values of heterogeneity factor of Freundlich isotherm are 2.59, 2.19, and 2.59 which are greater than 1, revealing the favorable adsorption of DMP/M-PVAL system. Values of adsorption activation energy per mole of Dubinin-Radushkevich isotherm are, respectively, of low values of 7.04, 6.48, and 7.19 kJ mol(-1), indicating the natural occurring of the adsorption process studied. The tiny size of adsorbent makes the adsorption take place easily while its superparamagnetism is beneficial for the separation and recovery of micro adsorbent from liquid by applying magnetic field after completion of adsorption.

摘要

采用磁性聚乙烯醇吸附剂M-PVAL去除并富集邻苯二甲酸二甲酯（DMP）。M-PVAL是在依次合成磁性Fe3O4（M）和聚醋酸乙烯酯（M-PVAC）后制备的。M、M-PVAC和M-PVAL的饱和磁化强度分别为57.2、26.0和43.2 emu g(-1)，均具有超顺磁性。M-PVAL的数量平均粒径为0.75μm，属于微米级。吸附实验包括三种情况：（1）将溶液的初始pH（pH0）调节至5；（2）不调节pH0，其值在6.04 - 6.64之间；（3）将pH0调节为7。Langmuir等温线单分子层的相应饱和吸附量分别为4.01、5.21和4.22 mg g(-1)。Freundlich等温线的非均质性因子值分别为2.59、2.19和2.59，均大于1，表明DMP/M-PVAL体系具有良好的吸附性能。Dubinin-Radushkevich等温线每摩尔的吸附活化能值分别为较低的7.04、6.48和7.19 kJ mol(-1)，表明所研究的吸附过程是自然发生的。吸附剂的微小尺寸使得吸附易于发生，而其超顺磁性有利于在吸附完成后通过施加磁场从液体中分离和回收微量吸附剂。
