Popis: 讨论了以TAN为衍生试剂,用Triton X-114非离子表面活性剂浊点萃取富集铁(Ⅱ )、钴(Ⅱ )、镍(Ⅱ )的各种条件,并于ODS柱上,用内含4.5 m mol • L-1十六烷基三甲基溴化铵(CTMAB)和0.03 mol • L-1 pH5.5HAc-NaAc缓冲溶液的甲醇/水溶液(体积比为69 : 31)作流动相,检测波长为565 nm,流速为0.8 mL • min-1,发展了浊点萃取-高效液相色谱法测定铁、钴、镍的新方法.在选定条件下,大多数离子不干扰测定,方法灵敏度高,对铁、钴、镍的检测限分别为0.1,0.1,0.03 µg• L-1.方法用于水样中铁(Ⅱ,Ⅲ)、钴(Ⅱ)、镍(Ⅱ)的测定,结果令人满意.
