to determine trace Hg2+. The immobilization of GOx integrated traditional electrochemical polymerization with self- assembly technique. Aniline was chosen to be electropolymerized on the electrode..., such as the immobilization and the buffer solution[18]. As reported previously, the pH range of a dissolved GOx from Aspergillus Niger is 3.4-7.5, while the pH range of GOx immobilized on activated carbon is 2.5-9[19......
-grafting method which was involved in the reaction of 2-aminomethylpyridine (AMP) with γ-chloropropyltrimethoxysilane (CPTS) prior to immobilization on the silica surface to synthesize a chelating... electrolyte. This novel chelating resin, denoted as Si-AMPY-1, was obtained by immobilization of a 2-aminomethylpyridine derivative, tert-butyl 2-picoly- amino-N-acetate (AMPY-1), onto the silica gel......
been employed for the immobilization of specific metals such as Cr(Ⅵ), U(Ⅵ), and Tc(Ⅶ) in groundwater[8-10]. Although many investigations have been reported on the use of SRB and ZVI respectively... the interaction between ZVI and SRB and its influence on the immobilization of U(Ⅵ). As shown in Table 2, the removal rate (R) of U(Ⅵ) in the ZVI+SRB combining reactor is obviously higher than......
to the inhibitor concentration that reduces the enzyme activity by half. 3 Biosensor preparation 3.1 Electrode preparation and immobilization of lactate dehydrogenase CHI Model 800B electrochemical analyzer... was used for preparation of working electrode. The gold plate coated with PGA-PPY polymeric film was immersed into 25% glutaraldehyde solution for 3 h. The immobilization of enzyme onto glutaraldehyde......

(OH)2(AsO4)2·4H2O and Ca5(AsO4)3OH are found to be well crystallized and stable with low solubility and leachability under the conditions of high alkalinity [47,48]. Thus, immobilization of ABLFS...) to As(V) species and immobilization of ABLFS by in-situ conversion of As into stable Ca4(OH)2(AsO4)2·4H2O and Ca5(AsO4)3OH crystals are promoted to achieve low arsenic leaching toxicity and environmental......
