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. This was my first time doing field work in West Bengal, India, which followed attendance at a British Council Newton Bhabha Fund funded workshop on arsenic treatment plants hosted at CSIR-Central Glass & Ceramic Research Institute in Kolkata.
