Abstract
Surface plasmon resonance (SPR) sensors have advantages of tracing heavy metal ions content and environmental monitoring. In this work, a surface plasmon resonance structure was built. it was based on Kretschmann structure which is cost-effective. The sensing layer were gold thin film deposited by sputtering technique. The resonance angles (θSPR) of heavy metal ions Pb+2, Zn+2 and Cd+2 were shifted to higher values with increasing their content. Complex refractive indices of metal ions were explored. The real and imaginary parts of refractive indices of heavy metal ions were increased while increasing their concentrations. Data curve fitting yields calculated θSPR any unknown concentration of heavy metal ions, also the performance factors were determined which predict the proper use of SPR sensor for different metal ions detection.
