| Abstract: | A method for determination of trace nickel in alloy by flow injection system of on-line ion-exchange preconcentration combined with flame atomic absorption spectrometry was established.In this experiment,sample and reagent flowed from the narrower end of the column to the broader end and the eluent flowed through it in the reverse direction by double-column to minimize dispersion,using 80 mesh 732 strong acid cation exchange resin in the 0.10mol/L HCl on-line ion-exchange enrich the Ni2+ of samples,and 2.0m... |
