摘要: The invention discloses a method for determining manganese content in hair, belonging to the technical field of analysis and testing trace elements. comprises steps of: acquiring piece hair 2cm away from occipital part head or back each ear, completely cleaning with neutral liquid detergent, drying, weighing certain amount sample, performing digestion treatment by using mixed sample-dissolving acid, then digesting sample atomic absorption spectrophotometry, wherein spectrophotometry determination experiment conditions, detecting method, recovery rate. disclosed has characteristics high sensitivity, good stability, risible results, simplicity rapidness operation, accuracy detection, capability meeting requirements daily physical examination manganese. A working curve made can be reused plurality times, operation frequency making day is reduced so that detection efficiency increased, scientific basis provided preventing poisoning occupational disease electric welders.
