Red cell granules: a new bio-absorbent for absorbing cyanide.
Granules of bovine and human red cells with a diameter about 4 mm and containing methemoglobin inside the cells were prepared artificially. These methemoglobin-containing red cell granules were very effective for detecting and absorbing cyanide in water. Each one g of red cell granules (wet weight) absorbed about 4 mg cyanide within an hour. An instant detector for cyanide was also devised by applying and gelling methemoglobin-containing red cells onto a filter paper. The granules may be useful for absorbing cyanide, which is used in large amounts in gilding factories and detoxified in water through complicated treatment systems.
