Abstract:
Objective To establish a rapid determination method for the exchangeable and reducible manganese.Methods In NH4Ac solution,manganese was determined by flame atomic absorption spectrophotometry.Results The linear ranges was 0.40-2.00 ?g/ml for exchangeable manganese and 100-5.00 ?g/ml for reducible manganese respectively.The detection limits were 0.012 ?g/ml for exchangeable manganese and 0.0078 ?g/ml for reducible manganese respectively.The RSDs were lower than 1.2%.The recovery rates were 100.2% for exchangeable manganese and 98.8% for reducible manganese respectively.The correlative coefficients were 0.9992 for exchangeable manganese and 0.9995 for reducible manganese respectively.Conclusion This method is rapid,simple,sensitive and accurate.
