A novel sensor based on carbon black-gold nanoparticle nanocomposite modified screen-printed electrode (CB-AuNPs/SPE) for the detection of As(III) has been developed. The sensor was prepared modifying the SPE with CB and AuNPs by a drop casting automatable deposition. The As(III) was detected by CB-AuNPs/SPE using anodic stripping voltammetry, with a high sensitivity (673 6 mAmM 1cm 2) and reaching a LOD of 0.4 ppb. Finally, CB-AuNPs/SPE has been applied to As(III) trace analysis in drinking water, obtaining satisfactory recovery values (99 9%).

Abstract
A novel sensor based on carbon black-gold nanoparticle nanocomposite modified screen-printed electrode (CB-AuNPs/SPE) for the detection of As(III) has been developed. The sensor was prepared modifying the SPE with CB and AuNPs by a drop casting automatable deposition. The As(III) was detected by CB-AuNPs/SPE using anodic stripping voltammetry, with a high sensitivity (673 6 mAmM 1cm 2) and reaching a LOD of 0.4 ppb. Finally, CB-AuNPs/SPE has been applied to As(III) trace analysis in drinking water, obtaining satisfactory recovery values (99 9%).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
