Cyclam‐Functionalized Silica‐Modified Electrodes for Selective Determination of Cu(II)

摘要: Cyclam derivatives have been grafted via 1, 2 or 4 silylated arms to the surface of mesoporous silica and resulting materials incorporated into carbon paste electrodes applied preconcentration electroanalysis Cu(II). Sensitive selective detection target analyte was achieved owing attractive binding properties this macrocyclic ligand towards Cu(II) species. Various parameters likely affect steps studied, including pH accumulation medium, composition solution, structure adsorbent, time, presence potentially interfering In particular, effect number groups linking macrocycle network on sensor performance discussed. After optimization, can be determined in a linear concentration range extending from 2 nM 100 μM. The method validated by reliable determination tap water.
