摘要：

The catalytic effect of manganese(II) on the oxidation of Rhodamine B with potassium periodate in the presence of 1,10-phenanthroline in acetic acid-sodium acetate was studied. A catalytic kinetic spectrophotometric method for determination of manganese(II) was developed, Manganese in the range 0.1-5.0 ng ml(-1) can be determined, and the detection limit is 0.02 ng ml(-1). Manganese in Chinese tea leaves was successfully determined.
