A survey has been made of methods available for the spectrophotometric determination of copper in fabrics treated with copper-containing fungicides. Seven of the most promising copper reagents were compared on the basis of sensitivity, simplicity of procedure, and specificity for copper in the presence of the metallic oxides used to render fabrics resistant to fire, ultraviolet light, and water. Methods employing rubeanic acid and zinc dibenzyldithiocarbamate offered the best combination of desirable characteristics.These methods proved to be as precise as the electrolytic method described in current federal specifications. These methods were also successfully tested against commercially treated fabrics obtained through actual Army procurements.Since only 3-5 mg of fabric are required for each determination, these spectrophotometric methods offer a means of determining the evenness of application of the fungicide on the fabric. The analysis of commercial fabrics treated with copper 8-quinolinolate and copper naphthenate indicated that the textile manufacturing industry is capable of obtaining a very even distribution of this mixture of fungicides throughout the material. Details of the rubeanic acid and zinc dibenzyldithiocarbamate methods are presented..
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
