Abstract
Using neutron activation analysis and radiotracers, the concentration variations of trace elements in sample and standard solutions caused by adsorption to storage bottles and by contamination with impurities due to leaching from laboratoryware were investigated. Concentrations of trace elements in aqueous solution varied with storage period, bottle material, and solution properties. The concentration variations slightly increased with storage period. In terms of concentration variations, nitric acid was better than hydrochloric acid for most elements. Also, it was found that high-density polyethylene and low-density polyethylene bottles are not good for storage of Sn. Contamination from impurities leached from laboratoryware (ion-exchange resins and filter paper) to solutions was investigated and found to be severe. Distribution ratios for almost all elements examined in this work were in the range of 10−3 g/ml.
