Comparative study of lignocellulosic biomass and its components as electrode modifiers for detection of lead and copper ions
Cellulose, xylan and lignin, as well as maize cell wall, were used as modifiers of carbon paste electrode. Comparative analysis of electrochemical performance of each modifier toward heavy metal detection was performed. A higher affinity of biomass constituents for lead ions than for copper ions inf...

Summary: | Cellulose, xylan and lignin, as well as maize cell wall, were used as modifiers of carbon paste electrode. Comparative analysis of electrochemical performance of each modifier toward heavy metal detection was performed. A higher affinity of biomass constituents for lead ions than for copper ions influenced simultaneous detection of lead and copper ions. The new procedure for the simultaneous detection of lead and copper ions based on their co-adsorption was presented.
•Biopolymers were used as modifier of carbon paste electrode.•Simultaneous detection of lead and copper ions was tested.•Biopolymer affinity for cations influenced simultaneous detection.•New procedure for simultaneous detection of lead and copper ions is presented.•The materials from renewable sources provide good alternative electrode materials. |
