摘要 |
Selected heavy metal compounds, particularly copper or nickel in the form of their salts, may be complexed with selected aliphatic or aromatic amines and deposited on a solid support or substrate to provide a material for the detection and/or removal of HCN from a mixture of gases; removal from tobacco smoke being particularly desirable. Certain novel compositions are also provided.
