Abstract:
A colotimetric method for the determination of nanogram amount of mercury based on the formation of the red complex with Thio-Michlers ketone is described. The pH of the solution is adjusted to 4~6 with a acetate buffer. The calibration curve for mercury was linear withina range of 0.515 ug/25m1(ε550nm = 1.5 × 105).
