The paper studies dissolved metals and suspended metals in industrial waste water which is filtered by membrane And the determination of 21 dissolved and suspended metals by ICP-MS. And also studies the detection limits, precision, Standard Recovery and other indexes of the measuring method. The linear course of the experiment were greater than 0.999 correlation coefficient, the relative standard deviation of each element（RSD%） were less than 4.0%, the recoveries of the elements are in the 89 ~112%. Experimental results show that the method has low detection limits, which can analyze multiple elements, and it has wide linear range of high precision, which can fast detect. The method can be used in the determination of dissolved and suspended metals in industrial waste water.
