Abstract:
Fast detection of Pb2+ pollution has become an important issue in the environment field and food industry. In this work, electrospun nanofibrous cellulose acetate/curcumin membranes (ENCACMs) and pure cellulose acetate (CA) membranes were fabricated by the electrospinning technique. Then the fast detection of heavy metals by these membranes was observed by naked eyes and digital camera. Fabricated ENCACMs showed obvious selectivity to the Pb2+ at pH 9. Pb2+ detection sensitivity of ENCACMs with a thickness of 0.2 mm was 1 mM (limit of detection) at pH 9. The sensitivity depended on the pH of solution and membrane thickness. However, it was not incubation time dependent. This work provides a simple, cheap, and fast method for detecting Pb2+. Moreover, this method is environmentally friendly to the detection solution and is simply post-treated after the detection process.

Common Ion Effect
Ions as Acids and Bases
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:
