Long-Term Stability of Low-Concentration Chromium Solutions in Glass and Polyethylene Containers.
Abstract
The stability of chromium solutions of low concentration (50 microg/dl), stored in either borosilicate glass or polyethylene containers previously subjected to a variety of surface treatments, has been evaluated over a period of 6 months. Polyethylene containers are not appropriate for storage of chromium solutions of low concentrations. Effects of surface adsorption, leading to significant losses in concentration, become obvious within 2 weeks in polyethylene vessels. Borosilicate glass containers, washed with water, are preferred for storage of such solutions for up to 6 months. Acid-washed and acid washed-basified-siliconized borosilicate glass vessels are equally satisfactory for the storage of Cr(+6) solutions of low concentrations. (Author)
