| Abstract: | A new exopolymers PF-2 was prepared for separation-preconcentration of trace nickel,and characterized using scanning electron microscope(SEM),energy dispersive X-ray spectrometry(EDX) and Fourier transform infrared spectrophotometry(FTIR).By means of the determination of flame atomic absorption spectrometry(FAAS),the adsorption behavior of exopolymers PF-2 for nickel ions was investigated.The results showed that at the optimum pH 5.0,the Langmuir isotherm fitted well with the experimental equilibrium data,a... |
