A specially designed high resolution ICP-MS was combined with an ultrasonic nebulizer to analyze trace amounts of various inorganic contaminants contained in water samples. It was confirmed that the detection limits of most elements obtained by the proposed method were well under 1 ppt. The Standard Reference Material 1643b (trace elements in water) provided by NIST (National Institute of Standards and Technology, formerly U. S. National Bureau of Standards) was also analyzed. Concentration values obtained by this work were in good agreement with certified values for all the elements examined except for Cu. It can be concluded from the foregoing that the combination of the above two instruments materializes an extraordinarily sensitive method and paves the way for direct determination of a considerable number of trace and ultra-trace elements in water samples with acceptable speed and accuracy.

A subject for the rapid determination of iodine content in drinking water by isopropyl sensitization and ICP-MS was established. The samples were dissolved in 1% ammonia solution, 127I was selected as the mass number to be measured and 159Tb as an internal standard. At the same time, 4% (V/V) isopropanol was used to enhance aerosol gasification efficiency, 2% NH3·H2O was used to effectively eliminate memory effects of iodine by cleaning sample for 180 seconds. The results show that, the detection limits of iodine in this method are 0.007 mg·kg-1 and it is superior to other literature. The standard curve has a good linear relationship and the recovery rates of testing rusults range are from 96.00% to 112.3%. The content of iodine in standard substance water samples was determined by ICP-MS method. The iodine content in water samples from seven drinking water sources in Lianyungang area was analyzed between 14~21 μg·L-1. It was in line with the allowable value of 10~300 μg·L-1 of the sanitary standard for drinking water, suggesting that the iodine content of drinking water resources in Lianyungang area was in a safe range.
