Abstract
The pencil graphite electrode modified with gold nanoparticles can be used for the detection of hydrazine. The pencil graphite electrode has an outer surface coated with gold nanoparticles. Prior to modification of the pencil graphite electrode, equal volumes of an aqueous solution of ascorbic acid and an aqueous solution of gold(III) chloride are mixed to form a mixture containing gold nanoparticles. A pencil graphite electrode is then immersed in the mixture and is heated at a temperature of about 75° C. to form the pencil graphite electrode coated with gold nanoparticles. The pencil graphite electrode coated with gold nanoparticles is then removed from the mixture, washed and dried, and may then be used for the to electrochemical detection of hydrazine.
