ABSTRACT
Objective To establish the methods for direct determination of manganese in the urine by flame atom absorption spectrophotometry (AAS). Methods Manganese in the urinary samples were determined directly and the result was compared with that by acid digestion. Results The results showed a good linearity, from 0.01 to 0.80 ?g/ml, r=0.9997, y=0.001 87+0.785 3 x. For the same urinary sample, the average urinary manganese content was 0.027 ?g/ml, standard deviation was 0.000 015 ?g/ml, RSD=0.056%. The average recovery rate was 95.1%. No significant difference was seen compared with the acid digestion. Conclusion The direct determination of urinary manganese by AAS is simple, rapid, accurate and feasible.
