| Abstract: | In HAc-NaAc solution trace Mn(II) catalyzes strongly decolorization reaction of bright green SF(BGSF) by oxidizing with potassium periodate and its catalytic extent is linear with the contents of Mn(II) in the certain range. Based on this study, a catalysis spectrophotometric method for determining trace Mn(II) was developed. The results show that the maximum absorption of the complex is at 651 nm and the detection limits of the method is 0.060 microgram.L-1 for Mn(II) and Beer's law is obeyed for Mn(II) in the range of 0.03-0.3 microgram.50 mL-1. The method has been applied to the determination of trace Mn in coal gangue with satisfactory results. |
