In order to enhance the sensitivity of mercury, the most effective reductant, tin(II) chloride was added to a mercury solution, and the mixture was immediately introduced into the plasma through a conventional pneumatic nebulizer. The attainable detection limit for mercury was inproved from 79 ng ml−1 in the untreated solutions to 1.3 ng ml−1 when tin(II) chloride was added. The present method was successfully applied to the determination of trace concentrations of mercury in several samples of waste water.
