摘要
以邻甲氧基苯胺为单体,通过化学氧化聚合法合成了单宁酸/硫酸掺杂聚邻甲氧基苯胺（POMA-H-GA）,采用FTIR、XRD、SEM及BET对其结构进行了表征。通过平衡吸附实验考察了POMA-H-GA对Cr^（3＋）的吸附性能,并以其为指标优化了Cr^（3＋）溶液初始质量浓度、时间、温度、pH。结果表明：POMA-H-GA在Cr^（3＋）初始质量浓度为0.1 g/L、时间3 h、温度25℃、pH=3.0~4.5时,吸附量为18.2 mg/g,吸附率达到93.2%,POMA-H-GA对几种重金属离子的吸附量大小顺序为Cr^（3＋）〉Hg^（2＋）〉Pb^（2＋）〉Cd^（2＋）。
Gallotannic acid and sulphuric acid doped ploy（o-methoxyaniline） composite（POMA-H-GA） was prepared by chemical oxidation polymerization using o-methoxyaniline as monomer. The sample was characterized by FTIR, XRD, SEM and BET. Adsorption of POMA-H-GA on Cr^（3＋） was investigated by equilibrium adsorption experiment. The factors affecting Cr^（3＋） adsorption were studied, such as Cr^（3＋） initial mass concentration, adsorption time, adsorption temperature and pH. The results showed that the adsorption capacity of POMA-H-GA on Cr^（3＋） achieved 18.2 mg/g and the adsorption rate was 93.2% when the Cr^（3＋）initial mass concentration was 0.1 g/L, the adsorption time was 3 h, the adsorption temperature was 25 ℃, and the pH was in the range of 3.0 to 4.5. In addition, the adsorption capacity of POMA-H-GA for several heavy metal ions was in the order of Cr^（3＋）Hg^（2＋）Pb^（2＋）Cd^（2＋）.
