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