摘　　要：氢卤酸、硝酸、硫酸、磷酸和硼酸处理的笼形聚偕胺肟树脂（ＨＸ／Ａ－ＣＡＯ）对Ａｇ＋和等贵金属离子的吸附能力按如下顺序：ＰｄＣｌ４２－：Ｈ３ＢＯ３／ＡＣＡＯ＞ＢＣＡＯ＞Ｈ３ＰＯ４／ＡＣＡＯ＞ＨＩ／ＡＣＡＯ＞Ｈ２ＳＯ４／ＡＣＡＯ＞ＨＣｌ／ＡＣＡＯ＞ＨＮＯ３／ＡＣＡＯ＞ＨＦ／ＡＣＡＯ．ＩｒＣｌ６２－：ＢＣＡＯ＞Ｈ３ＰＯ４／ＡＣＡＯ＞Ｈ３ＢＯ３／ＡＣＡＯ＞ＨＣｌ／ＡＣＡＯ＞ＨＦ／ＡＣＡＯ＞ＨＩ／ＡＣＡＯ＞Ｈ２ＳＯ４／ＡＣＡＯ≥ＨＮＯ３／ＡＣＡＯ．ＰｔＣｌ６２：ＢＣＡＯ＞Ｈ３ＢＯ３／ＡＣＡＯ＞Ｈ２ＳＯ４／ＡＣＡＯ＞ＨＮＯ３／ＡＣＡＯ＞ＨＣｌ／ＡＣＡＯ＞ＨＦ／ＡＣＡＯ＞Ｈ３ＰＯ４／ＡＣＡＯ＞ＨＩ／ＡＣＡＯ．Ａｇ＋：ＢＣＡＯ＞Ｈ３ＢＯ３／ＡＣＡＯ＞ＨＩ／ＡＣＡＯ＞Ｈ２ＳＯ４／ＡＣＡＯ＞ＨＦ／ＡＣＡＯ＞ＨＣｌ／ＡＣＡＯ＞Ｈ３ＰＯ４／ＡＣＡＯ＞ＨＮＯ３／ＡＣＡＯ．ＡｕＣｌ４－：ＢＣＡＯ＞Ｈ３ＢＯ３＞Ｈ３ＰＯ４／ＡＣＡＯ＞ＨＦ／ＡＣＡＯ＞ＨＣｌ／Ａ－ＣＡＯ＞Ｈ２ＳＯ４／ＡＣＡＯ＞ＨＩ／ＡＣＡＯ＞ＨＮＯ３／Ａ－ＣＡＯ．研究了Ｈ３ＢＯ３／ＡＣＡＯ树脂对Ａｇ＋和离子的吸附动力学，讨论了吸附机理．The adsorption properties of 'cage' polyamidoxime adsorbents treated with halogen acids, nitric acid, sulfuric acid, phosphoric acid and boric acid (HX/ACAO) for noble metals were investigated. The orders of adsorption capacity were found as follows:PdCl42-: H3BO3 /ACAO > BCAO > H3PO4/ACAO > HI/ACAO> H2SO4/ACAO >HCl/ACAO>HNO3/ACAO>HF/ACAO.IrCl62-: BCAO >H3PO4/ACAO>H3BO4/ACAO>HCl/ACAO>CAO>H2SO4/ACAO≥HNO>ACAO.PtCl62-: BCAO > H3BO3/ACAO > H2SO4/ACAO > HNO3/ACAO> HCl/ACAO >HF/ACAO>H3PO4/ACAO>Hl/ACAO.Ag+: BCAO > H3BO3/ACAO> HI/ACAO> H2SO4/ACAO> HF/ACAO> HCl/ACAO>H3PO4/ACAO>HNO/ACAO.AuCl4-: BCAO > H3BO3/ACAO > H3PO4/ACAO > HF/ACAO > HCl/ACAO >H2SO4/ACAO>HI/ACAO>HNO4/ACAOThe adsorption kinetics of PdCl42-, IrCl62-, PtCl62-, Ag+, and AuCl4-. ions adsorbed on H3BO3/ACAO resin were studied, and the adsorption mechanism was proposed and discussed.
