ICP-AES Determination of Sulfide and Sulfate Content in Pebble and Crushed Stone

Abstract:

Generally, the content of sulfide and sulfate (expressed as a sulphur trioxide) in pebble and crushed stone for construction is low. So use the weight method specified in the national standard method for determination, is not only tedious and time consuming, but also not accurate enough. In this paper, with reference to the pretreatment method of the relevant national standard, rapid and accurate test results can usually be obtained for the determination of sulfur trioxide in and crushed stone for construction by using ICP-AES as a new method, greatly reducing the time of the experiment and improve the efficiency. According to the analysis of spectrum interference, 182.0 nm was selected as the best analysis of spectral line for sulfur. The detection line of this method (3S) was 0.016 mg/L, the recovery rate of the sample was between 93.3%-104.0%, and the relative standard deviation (n=6) of the parallel samples was less than 1.05%.
