Abstract
A disposable paper-based sensor (PBS) is described for the determination of Cu(II) in natural and waste waters at approximately 2 cents per measurement. The device makes use of a polymer inclusion membrane (PIM) to provide the selectivity for Cu(II). The PIM consists of 40wt% di(2-ethlyhexyl) phosphoric acid (D2EHPA) as the carrier, 10wt% dioctyl phthalate (DOP) as a plasticizer, 49.5wt% poly(vinyl chloride) (PVC) as the base polymer and 0.5wt% (mm-1) 1-(2'-pyridylazo)-2-naphthol (PAN) as the colourimetric reagent. High selectivity under mildly acidic conditions (HCl, pH 2.0) is achieved for Cu(II) in the presence of frequently encountered metal ions in natural and waste waters such as Fe(II..
