Sol-gel Approach in Molecular Imprinting for Crystal Violet Selective Recognition

A limitation of conventional MIP in thermal and mechanical stabilities condition, improper porosity low adsorption capacity, give a reason to introduce sol-gel method molecular imprinting process recently. In this study, synthesis new molecularly imprinted polymer (SG-MIP) was studied for crystal violet (CV) selective recognition. The control non-molecularly (SG-NIP) also synthesized as reference. preparation SG-MIP introduced by combination the organic inorganic mixture. solution included methacrylic acid, trimethylolpropane trimethacrylate, benzoyl peroxide which are monomer, crosslinker, initiator, respectively. involved ratio tetraethyl orthosilicate: ethanol (1:1 v/v). functional group analysis proved successful SG-NIP. indicated high stability SG-NIP, morphology surface analyses showed respective different structures, surface, values between influence selectivity study behaviour toward CV adsorption. result verified that (4.900 mgg-1) has higher characteristics compared SG-NIP (4.432 mgg-1). equilibrium data kinetic isotherm studies were well-fitted pseudo-second order model (R2 = 0.9997 R2 0.9996) Freundlich 0.9500 0.9764), supported Scatchard plot instead Langmuir model.
