Objective To establish a method for the determination of cadmium in soil by rapid digestion-graphite furnace atomic absorption spectrometry( GFAAS). Methods The soil samples were conducted for rapid digestion on the graphite digestion instrument at 120 ℃ for 1 hour,quantified with deionized water after cooling down,and then detected by GFAAS.Results The soil cadmium standard sample was pretreated by electric heating plate wet digestion method,microwave digestion method and graphite rapid digestion method.
