The method for analysis of transition metal ions (Zn(II), Cu(II), Со(II), Ni(II), Fe(III)) by high-performance planar (thin layer) chromatography with the use of sorbents modified by chelating fragments of iminodiacetic acid was developed. The correlation between retention factor (Rf) and physico-chemical parameters of the separated systems was studied. It was demonstrated that unlike the pH value, ionic strength of a solution does not exert significant influence on resolution and mobility of transition metal cations
