A solid phase extraction procedure based a column technique for preconcentration of
lead, iron, manganese and zinc from water samples was developed. The analyte ions as its
diethyldithiocarbamate complex were retained on a column of Chromosorb 105 from buffered
sample solution. Then they were eluted with acetone. The recoveries of lead, iron, manganese
and zinc under the optimum working conditions were 100, 97, 100 and 100%, respectively. The
relative standard deviations were less than 6%. The method presented was applied for the
determination of lead, iron, zinc and manganese in sea water samples.
