TiO2 beads and TiO2-chitosan beads for urease immobilization
(Elsevier Science Bv, 2014)The aim of the present study is to synthesize TiO2 beads for urease immobilization. Two different strategies were used to immobilize the urease on TiO2 beads. In the first method (A), urease enzyme was immobilized onto ... -
Ultra-Trace Determination of Arsenic by Platinum-Coated Tungsten Coil Hydride Generation (HG) Atomic Absorption Spectrometry (AAS)
(TAYLOR & FRANCIS INC, 2022)A simple, rapid, and sensitive method for the determination of ultra-trace arsenic (III) is reported based on in situ trapping and revolatilization on a platinum (Pt) coated tungsten (W) coil atom trap. First, the analyte ... -
Ultra-trace determination of mercury by platinum-coated tungsten coil trapping cold vapour atomic absorption spectrometry
(TAYLOR & FRANCIS LTD, 2022)Within the scope of this study, a simple, highly sensitive and rapid trapping method for the determination of mercury (Hg) was developed. In this method, the surface of the tungsten coil (W-coil) was coated with platinum ... -
Urease immobilized core–shell magnetic Fe[NiFe]O4/alginate and Fe3O4/alginate composite beads with improved enzymatic stability properties: removal of artificial blood serum urea
(Springer, 2021)The present study consists of the preparation of core–shell magnetic carriers with alginate and magnetic nanoparticles (Fe3O4 and Fe[NiFe]O4) using for these carriers (MA—magnetite alginate and NFA—nickel ferrite alginate) ... -
Urease immobilized electrospun PVA/chitosan nanofibers with improved stability and reusability characteristics: an application for removal of urea from artificial blood serum
(Taylor & Francis Inc, 2020)Electrospun polyvinyl alcohol (PVA)/Chitosan nanofibers were successfully prepared and were used as carriers for the first time in urease immobilization. Also, urease immobilized electrospun PVA/Chitosan nanofibers were ...
