Colorimetric detection of copper ions in tap water during the synthesis of silver/dopamine nanoparticles.
A facile, economic and eco-friendly colorimetric sensor for Cu(2+) using dopamine/silver nanoparticles was developed. The sensor shows excellent sensitivity and selectivity toward Cu(2+) in the range of 3.2-512 ppb and can be applied for Cu(2+) detection in tap water.
