A carbon paste electrode modified with poly(methylene disulfide) nanoparticles for anodic stripping voltammetric determination of silver(I).

Poly(methylene disulfide) nanoparticles (PMDSNPs) were synthesized and characterized by FTIR, FESEM, EDX, and TGA. The nanomaterial was used to modify a carbon paste electrode to obtain a sensor for differential pulse anodic stripping voltammetric analysis of silver ion. The silver ions are accumulated on the modified electrode by reduction at a potential of -0.
