| 摘 要： | 将锆的水合氧化物固载于大孔螯合树脂D401上制备出一种新型除砷材料,并研究了不同实验条件下复合吸附剂D401-Zr对水溶液中As(V)的吸附性能。研究结果表明,在pH<5.2时D401-Zr对As(V)都具有较强的吸附性能;其吸附等温线与Langmuir吸附模型具有较高的吻合度;吸附动力学研究表明,D401-Zr对砷的吸附均遵循二级动力学方程;竞争吸附实验表明,与SO24-、Cl-共存时,D401-Zr对砷的去除率大于90%,而与PO34-、F-竞争离子共存时,其去除率明显下降。 |

| Abstract: | The hydrated zirconium oxide was loaded successfully onto the D401 chelating resin to obtain a new sorbent named D401-Zr. The removal of As(V) by using D401-Zr under different experiment conditions was studied. The results indicated that D401-Zr has a good adsorption capacity to As(V) at pH<5.2. The static experiment data also demonstrated that the adsorption isotherm presented a good fitting to Langmuir model. The kinetic data of the D401-Zr adsorption to As(V) could be described by the Lagergren second-order rate equation well. The removal rate of D401-Zr to As(V)still reached more than 90% in the presence of the competing anions such as SO42- and Cl-, but PO43- and F- had a strong inhibition on As(V), which would cause the removal rate to decrease clearly. |
