Abstrakt:	The promising sensing properties of sulphaquinoxaline Cd(II) complex towards Cd(II) were reported via the fabrication of polyvinyl chloride (PVC) and modified carbon paste (MCP) electrodes. The developed sensors applied for Cd(II) determination in water, tea, rice, and cosmetic samples exhibited excellent performances with detection limits of 8 × 10–7 and 2.1 × 10–7 M as well as fast response time (about 10 s) for MCP and PVC sensors, respectively. No significant changes in the Nernstian slope by changing the solution pH in the ranges of 4.0–9.0 and 3.0–6.5 for MCP and PVC electrodes, respectively, or by rising the temperature to 60°C were observed.
