Voltammetric measurement of copper(II) using modified carbon paste electrode with zinc layered hydroxide2(3-chlorophenoxy) propionate nanocomposite (IR)

A multi-walled carbon nanotube (MWCNT) paste electrode modified with zinc layered hydroxide-2(3 chlorophenoxy)propionate (ZLH-CPPA) nanocomposite was evaluated for the voltammetric determination of Cu(H). Experimental conditions were used percentage of modifier, supporting electrolyte, pH and scan r...
