The solid phase extraction was performed in batch mode and the determination of the analyte in the solid phase was easily carried out by introducing a slurry of the yeast (0.0625 g / 2.5 mL) directly into the ICP OES. A limit of detection of 0.11 µg L-1 and a sample throughput in the range of 4 - 54 sample h-1 were obtained. Determinations of cadmium in a certified sample and in real river water samples were in excellent agreement with the expected values.323-326porsolid phase extractioncadmiumyeastPré-concentração de cádmio com Saccharomyces cerevisiae e determinação em águas fluviais usando espectrometria de emissão óptica com plasma indutivamente acopladoPreconcentration of cadmium with Saccharomyces cerevisiae and determination in river water using inductively coupled plasma optical emission spectrometryArtigo10.1590/S0100-40422007000200016S0100-40422007000200016Acesso abertoS0100-40422007000200016.pdf63488355397449840000-0003-2774-9727
