Heavy metals at low concentrations can have a damaging effect in chemical and optical bleaching of textile materials. The application of anodic stripping voltametry for determining copper and iron in textile materials is described. The preparation of the samples of cotton, wool, polyester, polyamide, and polyacrylics, and procedures for determining copper and iron in these materials are reported. See also AATA 21-1801 for study of optical bleaching effects. -- AATA
