| Abstract: | Determination of manganese in bauxite with a new catalytic spectrophotometry is established. The linear scope of the method is 0μg/L～3.2μg/L, measurement limit is 3.5×10^-6g/L, relative standard deflection is RSD = 0.93% （n = 11 ）, recovery rate is 98.00% - 100.33% and the measurement result is in conformity with the national standard method. It has the characteristics of easy operation, accurate result and good repetition rate determining manganese in bauxite with such method. |
