    Recovery of Cr(VI) by using a novel calix[4]arene polymeric membrane with modified graphene quantum dots
    (Springer, 2017) Onac, C.; Kaya, A.; Alpoguz, H. K.; Yola, M. L.; Eriskin, S.; Atar, N.; Sener, I.
    In this report, the recovery of Cr(VI) from chrome plating water by using a novel calix[4]arene-functionalized graphene quantum dots (GQDs) involved polymer inclusion membrane was investigated. The polymeric membrane supported by GQDs was characterized by using Fourier transform infrared (FTIR), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The SEM and AFM results clearly show that there are much larger visible pores on the membrane surface after modification of polymer inclusion membrane with GQDs and the micropores in the membrane surface were vanished and performed with GQDs after modification of membrane. The transport efficiency of chromium was found to be 97.23% through the modified membrane from 0.1 M HCl as donor phase to pH 5 as an acceptor phase. The system is available for long-term usage. The highly selective and mechanical strength of membrane is developed by adding GQDs. Modified membrane exhibits significant stability and selectivity, and the system is used for the real samples.

    Removal of Reactive Yellow 86 using TiO2 nanoparticle-colemanite waste
    (Journal of Chemical Engineering Research Studies, 2014) Eren, T.; Törün, H.; Yola, M. L.; Ertan, B.; Atar, N.
    A novel composite containingTiO2 nanoparticles (TiO2NPs) and colemanite waste (CW) was synthesized and tested in adsorption and photocatalysis to remove Reactive Yellow 86 (RY86) from aqueous solution. Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction patterns (XRD) showed the formation of metal TiO2 NPs on CW. The BET surface area increased after intercalation of TiO2 NPs onto CW. TiO2 -CW was found to be a good nanomaterial for RY86 adsorption. The effects of operating variables such as initial dye concentration, pH and contact time in adsorption were studied. The kinetics, isotherm and thermodynamic parameters for the removal of the RY86 were also investigated. In addition, TiO2 -CW also shows high photocatalytic activity for degradation of RY86 from aqueous solution. The combination of adsorption and photocatalysis using TiO2 -CW is demonstrated as a more effective technique for removal of dyes from aqueous solution.
