摘　　要：采用液相色谱流动相为0.05mol·L^(-1)草酸和0.095mol·L^(-1)氢氧化锂,流速为1.0ml·min^(-1);柱后衍生试剂为0.001mol·L^(-1)PAR+0.3mol·L^(-1)氨水+0.1mol·L^(-1)乙酸,流速为1.0ml·min^(-1),进样体积为20μl,检测波长为500nm,同时对Pb^(2+)、Cu^(2+)、Cd^(2+)、Co^(2+)、Zn^(2+)和Ni^(2+)检测。方法可用于水样检测。It is reported that Pb^(2+) Cu^(2+) Cd^(2+) Co^(2+) Zn^(2+) and Ni^(2+) are determined simultaneously by the liquid chromatographic-post column derivation method. A solution containing 0.50mol ·L^(-1) of oxalic acid and 0. 095mol ·?L^(-1) of lithium hydroxide is used as the mobile phase. Reagents used in the post column derivation are 0. OOlmol ·L^(-1) PAR, 0. 3mol ·L^(-1) ammonia water and 0. lmol ·L^(-1) acetic acid. Both of the speed of the mobile phase and the derivation solution are 1.0ml ·min^(-1). This method can be used in water analysis.
