Performance of the 10 wt % poly(BPE)/g-C₃N₄ composite-modified GCE for individual and simultaneous determination of Cd²⁺ and Pb²⁺.

Types	Analytes	Linear Range (μM)	Linear Regression Equation	R²	Detection Limit (μM)
Individual determination	Cd²⁺	0.1–6.8	I (μA) = 1.08782 + 7.63612c (μM)	0.99707	0.00970
Individual determination	Pb²⁺	0.1–6.4	I (μA) = 0.37986 + 11.1397c (μM)	0.99661	0.00327
Simultaneous determination	Cd²⁺	0.12–7.2	I (μA) = 0.26776 + 4.11513c (μM)	0.99740	0.0180
Simultaneous determination	Pb²⁺	0.08–7.2	I (μA) = 0.73646 + 11.28023c (μM)	0.99599	0.00324
