Voltammetric behavior and trace determination of cadmium at a calixarene modified screen-printed carbon electrode (2002)
Journal Article

Screen-printed carbon electrodes (SPCEs) have been evaluated for the anodic stripping voltammetric determination of cadmium using open circuit accumulation facilitated by two different calixarenes: a novel thiolated calixarene, calixarene (I), (5,11,...

Towards the development of molecularly imprinted polymer based screen-printed sensors for metabolites of PAHs (2001)
Presentation / Conference Contribution

This paper describes the fabrication of a sensor for 1-hydroxypyrene (1-OHP) based on a screen-printed carbon electrode (SPCE) modified with a molecularly imprinted polymer (MIP); 1-OHP was chosen as a model metabolite of polyaromatic hydrocarbons (P...

Voltammetric studies of lead at a 1-(2-pyridylazo)-2-naphthol modified screen-printed carbon electrode and its trace determination in water by stripping voltammetry (2001)
Journal Article

A method for the trace determination of Pb2+, using a disposable 1-(2-pyridylazo)-2-naphthol (PAN) drop-coated modified screen-printed carbon electrode (PAN-SPCE), has been developed. Lead ions (Pb2+) are accumulated from ammonia buffer, on the PAN-S...

Voltammetric behavior and trace determination of lead at a mercury-free screen-printed carbon electrode (2000)
Journal Article

Abstract Screen-printed carbon electrodes (SPCEs), without chemical modification, have been investigated as disposable sensors for the measurement of trace levels of Pb. Cyclic voltammetry was employed to elucidate the electrochemical behavior of Pb...
