Glass is a notorious source of metal ion contamination. Three
glass bottles were crushed and sieved to collect 1-mm pieces.26 To
see how much Al3
could be extracted, 200 mL of a 0.05 M solution of the metal-binding compound EDTA were stirred with 0.50 g
of ~1-mm glass particles in a polyethylene flask. The Al content of
the solution after 2 months was 5.2 M. The total Al content of the
glass, measured after completely dissolving some glass in 48 wt%
HF with microwave heating, was 0.80 wt%. What fraction of the Al
was extracted from glass by EDTA?
