Abstract
Spectrographic determination of manganese quantity in blood, urine and feces of normal male has been studied, in order to examine the occupational manganese poisoning, because of its trace amonut of contents, restriction of the sampling quantity and also of easy operation of the sample. Sample blood was dried, and sample urine and feces were dried to ashes, and they are discharged between graphite powder electrode, either copper or lithium carbonate being used as an internal standard material and crater graphite electrode with alternating current are of 220V, at 68A and the calibration was made according to the Seidel density method.The results show that it is determined in the range of 0.01ppm with 24 ml of sample bIood and 0.001ppm with feces, with 1020% precision.
