|Abstract:||A procedure for the direct determination of tin in biological samples is described. Based on the formation of the adsorptive complex of tin with 8-hydroxyquinoline (oxine), it is possible to determine subnanomolar levels of tin after a few minutes of stirred accumulation at -0.25 V. The detection limits are 0.35 nM (40 ppt) and 70 pM (8.3 ppt) for 1- and 5-min accumulation periods, respectively. The standard deviation at 50 nM is 1.4%. Possible interferences were investigated. This procedure was applied to determine trace amounts of tin in blood, serum and plants.|
