Abstract

Polymer inclusion membranes (PIMs) containing commercial dinonylnaphthalene sulfonic acid (DNNS) as the carrier were studied to ascertain their potential for use as the semi-permeable barrier in a passive sampler for the accumulation of ammonia. Extensive screening of membrane compositions using cellulose triacetate (CTA) and poly(vinyl chloride) (PVC) as the base polymers and different plasticizers/modifiers (i.e. 2-nitrophenyloctylether (NPOE), dioctyl phthalate (DOP) and 1-tetradecanol) was conducted and successful membranes were studied for their ability to extract and back-extract ammonia using a 3.00mgL-1 NH4+ aqueous feed solution and 1.0molL-1 HCl aqueous receiving solution. The CTA ..
