A Novel Molecularly Imprinted Acrylonitrile-butadiene-styrene Membrane for Adsorption of Hippuric acid

The abundance of electronic waste has now become a major problem. For sustainability and waste to wealth, the concept of reuse, refurbished and recycled has been forwarded. In this research the electronic waste ABS plastic was recycled and molecularly imprinted for fast, sensitive, selective and robust absorption membrane. The extraction of biological fluid has always being a challenge with the emulsification of solvent and destruction of sorbent pack. Thus, using the developed molecularly imprinted polymer membrane (MIP ABS), adsorption of hippuric acid is studied. For optimization the parameters that influenced the adsorption efficiency were also investigated. For comparison the non-molecularly imprinted membrane (NIP ABS) used as blank was also prepared. This study, the standard calibration curves of 5 mg/L to 40 mg/L of hippuric acid against the MIP and NIP ABS were obtained. The coefficients determination R2for MIP ABS were 0.9994 and with the regression equation of y = 28845x –16638 respectively. This research also found that pH 6 of the sample solution was the optimized condition with recovery percentage of 98.56%. hippuric acid bound with the MIP ABS membrane.
