摘要
将橘子皮用氢氧化钾、乙醇和氯化钙进行皂化处理,得到改性橘子皮生物吸附剂(SCOP)。在保持p H、起始金属离子浓度和温度不变的情况下进行吸附试验,研究不同氢氧化钾浓度浸泡下的SCOP及不同固液比、接触时间的改性橘子皮对水中锌、铁离子的吸附量大小。通过火焰原子吸收分光光度计定性测得SCOP对锌离子有较好的吸附,对铁则吸附较少。
A novel absorbent was prepared by modifying orange peel with potassium hydroxide and calcium chloride. Keeping pH, initial concentration of metal ions and experimental temperature not change, the absorption behavior of Zn（Ⅱ） and Fe （Ⅱ） on modified orange peel under varying concentration of sodium hydroxide, contract time and absorption of different quantity were studied. SCOP had a better adsorption capacities for Zn （Ⅱ） but with a fewer for Fe （Ⅱ） by flame atomic absorption spectrometry.
