On-line speciation analysis of inorganic arsenic in complex environmental aqueous samples by pervaporation sequential injection analysis
2013
Abstract
A proof of concept of a novel pervaporation sequential injection analysis method for automatic non-chromatographic speciation analysis of inorganic arsenic in complex aqueous samples is presented. The method is based on hydride generation of arsine followed by its on-line pervaporation-based membrane separation and CCD spectrophotometric detection.
