One novel Cu(II)-Fe(III) heteronuclear complex [Cu2(oxen)Fe(CN)5(NO)]n (H2oxen = N,N'-bis(2-aminoethyl)oxamide) was synthesized by the reaction of Cu(oxen)·2H2O with Cu(ClO4)2·6H2O and Na2[Fe(CN)5NO]·2H2O. The crystal structure was determined by single-crystal X-ray diffraction. The complex crystallizes orthorhombic with space group Pnma, and forms a centrosymmetric Cu(II)-Fe(III) heteronuclear molecule...
Though neutralizing the H+ ions generated by water electrolysis in anode compartment can improve the current efficiency of electrokinetic remediation process, “dead zone” phenomenon close to anode cannot be mitigated due to the increasing of total ion concentration in anolytes. An effective method was to keep the ion concentration at a low level in the entire electrokinetic remediation process. Modifying...
This paper deals with the extracellular polymeric substance (EPS) of Rhizobium radiobacter F2 used as a novel biosorbent to remove Cu (II) and Mn (II) ions from aqueous solutions. The Cu (II) and Mn (II) ions biosorption characteristics of the EPS were examined as a function of initial pH, contact time and EPS concentration. The proper pH of the aqueous solution was found to be 6.0 for both the biosorption...
