A simple and rapid method has been developed to determine226Ra in rocks, soils, and sediments. Samples are decomposed by fusion with lithium metaborate and the melt is dissolved in a solution containing sulfates and citric acid. During the dissolution, a fine suspension of mixed barium and radium sulfates is formed. The microcrystals are collected on a membrane filter (pore size 0.1 μm) and analysed in an alpha spectrometer. Application of a133Ba tracer enables us to assess the loss of the analyte, which only rarely exceeds 10%. All analytical operations, beginning from sample decomposition to source preparation for alpha spectrometry, can be accomplished within 1 or 2 h.With uranium determination, the filtrate is spiked with a232U tracer and passed through a column loaded with a Dowex AG (1 x 4) anion-exchange resin in the sulfate form. Interfering elements are eluted with dilute sulfuric acid followed by concentrated hydrochloric acid. Uranium is eluted with water, electrodeposited on silver discs, and analysed in the alpha spectrometer. The method was tested on reference soil and sediment materials and was found to be accurate within the estimated uncertainties.

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.
