A new method for the solid phase extraction followed by high performance liquid chromatographic determination of lead, cadmium and mercury was studied. Lead, cadmium and mercury were pre-column derived by Tera-(4-Methylphenyl)-porphine (T 4MPP). These chelates can be extracted by Waters Sep-Park-C 18 cartridge and eluted by terahydrofuran (THF) (contain 0.01 mol/L prolidine-acetic acid buffer (pH=10)). The chelates can be separated on a Waters Xterra TM RP 18 chromatographic column (5 μm, 3.9×150)...
