The contents of Pb、Cd、Cr、Ni in sludge in wastewater treatment plant were determined by FAAS.To research the influence of cinefaction temperature,cinefaction time,and different nitrate acid volume of digestion on the absorption of different metals.Under the optimal conditions,the correlation coefficient of four elements were all between 0.997 0～0.999 9,and the recovery rates were between 96.0%～106.5%.The determined resuls were accuracy and precision.To get the changing concentrations of above elements in different seasons.
