Determination Of Copper

3,4-Diaminobenzenethiol can react with AuNPs via a strong covalent Au–S bond. The exposed amino functional groups on the benzene ring from neighboring AuNPs could bind to copper ions, resulting in AuNP aggregation.

Determination Of Copper

A new method for the solid phase extraction (SPE) and determination of copper ions at low levels is presented. Extraction percent and the effects of some factors were evaluated. The detection limit was in the range of 2.26 µg·L-1. This procedure has been successfully applied to determination of copper in water samples.
