A new detection method is established for MTs, in pH 2.5 buffer solution, the enhancement of RLS at 505 nm was proportional to the concentration of MTs, thus MTs was determined under the existence of arabirgum-polyvinyl alcohol-124 as a steady agent. The detection limit was 21.58 ng/mL with RSD 3.67% -5.61%, ranging from 0. 072 - 6.3 μg/mL（ r = 0. 994 9）, the average recovery was 95.6% （n = 6）. The method has been applied to the determination of me...
