摘要: 室温下柠檬酸在水溶液中可与Sb(III)和Sb(V)形成稳定络合物，使用高效液相色谱与电感耦合等离子体质谱仪联用，以5 mmol∙L−1乙二胺四乙酸二钠(EDTA-2Na)和3 mmol∙L−1邻苯二甲酸(调pH为4.5)为流动相，Sb(III)和Sb(V)的柠檬酸络合物在PRP-X100阴离子交换柱上达到基线分离，从而实现了海水中Sb(III)与Sb(V)的分离检测。
Abstract: Both Sb(III) and Sb(V) could form stable complexes readily with citric acid in an aqueous solution at room temperature. Sb(III)-citrate and Sb(V)-citrate were separated on a PRP-X100 anion-exchange column with 5 mmol∙L−1 EDTA-2Na and 3 mmol∙L−1 phthalic acid (pH = 4.5) being the mobile phase. Thus, a HPLC-ICP-MS analytical method for the speciation of Sb(III) and Sb(V) in seawater was de-veloped.
