ABSTRACT
A simple, rapid, microsampling method for the determination of zinc in relish by derivative FAAS is described. The influences of microsampling volume and other factors are discussed. The detection limit and sensitivity of the proposed method are 0.013 and 0.004 microg x mL(-1), respectively. The samples were centrifugalized and diluled with 1.5% HCl solution, and then analysized directly. The method was applied to the determination of zinc in relish with a recovery of 93.3%-113.3% and relative standard deviation of 3.0%-4.4%.
