Polyurethane nanocomposite for removal of Lead from water

The rapid growth of the human population as well as the released waste waters from various industries, demand for developing an adequate water purification method is necessary. In the past decades there are several methods had been reported in this area which all of them has their own merits and drawbacks namely additives additions into the water wastes and etc. which need some additional recovery and separation methods.In the recent years a well-known method has been developed for water purification based on using solid polymeric supports enable to capture heavy metals from water wastes.Among the tested variables, pH was found to be the most critical parameter for the adsorption of metals on nanocomposite. To evaluate the effect of pH on the retention efficiency, the pH of 10 mL of sample solution containing 5 mg L−1 of lead ions was adjusted to fit in the range of 4-7.In the current communication the performance of graphene oxide functionalized polyurethane rigid foam is evaluated for removing of heavy metals from drinking water through a cation exchange process is reported. In addition,Fourier transform infrared spectroscopy (FTIR), thermo gravimetric analysis (TGA), were used to characterize the foam and UV technique is done on the untreated and treated samples in order to evaluation of the foam performance.
