Immobilization of various ligands on Alumina surface for removal of some toxic cations

A micro column of alumina modified with sodium dodecyle sulfate and 1 - ( 2 - pyridylazo ) - 2 - naphtol and Dithizone and Dimetyl goly oxime were prepared for the preconcentration of trace some toxic cations such as Ni ( II ), Cr ( II ), Pb ( II ),Cd ( II ), Fe ( II ), Mn ( II ), Zn ( II ), from water sample and sewage for a flam atomic absorption spectrometry determination . Optimized conditions (pH; flow rate) cations were retained on the column. Recoveries were greater than 96 %.
