… This paper studies the detection of copper ions by using an iminodiacetatic acid (IDA) … ion
capture. The modified electrode was used for the electrochemical analysis of trace copper ions …

… The approach is based upon the deposition of a macroporous copper deposit which shows
marked selectivity for nitrate ion under mildly acidic conditions (pH 3) with a linear range …

… sensitive electrochemical sensor for the detection of copper ions based on the copper ion
assisted etching of Au@Ag nanoparticles was developed in this work. Since copper ions could …

Herein, for the first time, we engineered click chemistry reaction to trigger a 3D DNA walking
machine for ultrasensitive electrochemical detection of copper ion (Cu 2+ ), which provided …

… copper ions for 10 min and washed with copper-free ammonium acetate buffer. The bound
metal ions … −1.2 V for 120 s, and the electrochemical response was measured by square wave …

… for the direct electrochemical detection of Cu 2+ . The direct electrochemical response can
… different types of interfacial barriers can produce different detecting performance. This novel …

… An inferior stability, with a current diminution 38% and an repeatability of 20%, was found
for the copper paste electrode. This is possibly due to gradual loss of copper ions from the …

… illustrated by the case of lead and copper. Detection of lead in the presence of copper ions
is largely known to be complicated by the appearance of lead-copper species. Even though …

… was used firstly to detect individually and simultaneously various heavy metal ions. Furthermore,
CuNP… as a potential material to detect individually and simultaneously heavy metal ions. …

… Although electrochemical sensors based on polypyridyl metal complexes for anions have
long been known [112], the use of these metal complexes for the electrochemical detection of …
