A fast and simple dilute-and-shoot procedure for determination of Al, As, Ba, Cd, Cu, Fe, Mg, Mn, Ni, Pb, Sc, Ti, V, Zn and Zr in deodorants by inductively coupled plasma optical emission spectrometry (ICP OES) was developed. Sample preparation was carried out by diluting 1 mL of deodorant sample in 1% (v v) HNO. The accuracy of the analytical procedure was evaluated using addition and recovery experiments, and recoveries ranged from 80 to 119%. The limits of detection varied from 0.001 to 0.76 mg kg. Nine deodorants samples of different brands were analyzed. The maximum concentrations found (mg kg) were: Fe (1.0), Mn (0.1), Ti (1.02), V (0.33), Zn (255.2) and Zr (0.5); for Al and Mg, determined concentrations varied from 0.01 to 7.0% and from 0.005 to 1.44 mg kg, respectively, showing wide variation depending on the sample type. The developed procedure was adequate for determining these analytes in routine analysis presenting high sample throughput and demonstrated the feasibility of direct analysis measurements after simple dilution step.
