Description

We show how novel chemistry can be used to separate inorganic arsenic(III) and arsenic(V) – a material we have patented and named ImpAs, consisting of a arsenic(V)-selective metal-organic chemisorbent receptor supported on polymer resin beads. We show two cases studies as example applications for simple, portable and fast devices built on this technology: (1) to assess the toxicity of groundwaters, and (2) to monitor the progress of arsenic(III) photooxidation in the presence of a titanium dioxide (TiO2) photocatalyst.
