The asymmetric unit of the title compound, {[Pb(C(9)H(6)NO)(2)]·0.5C(3)H(7)NO}(n), comprises Pb(quinolate)(2) and half a dimethyl-formamide mol-ecule (which is disordered about a centre of inversion). The quinolate ligands N,O-chelate to a Pb(II) ion and simultaneously bridge a neighbouring Pb(II) ion to form a polymeric chain along [100] comprising Pb-linked Pb(2)O(2) distorted rhombi. These c...

A substantive approach converting waste date pits to mercerized mesoporous date pit activated carbon (DPAC) and utilizing it in the removal of Cd(II), Cu(II), Pb(II), and Zn(II) was reported. In general, rapid heavy metals adsorption kinetics for Co range: 25-100 mg/L was observed, accomplishing 77-97% adsorption within 15 min, finally, attaining equilibrium in 360 min. Linear and non-linear is...

In this study, the removal of Pb(II) from aqueous solutions by tassel powder was studied and optimised. Batch experiments were conducted on simulated solutions using tassel powder adsorbent and the effects of contact time, pH and concentration on the extent of Pb (II) removal was studied. Equilibrium and kinetic models for Pb(II) sorption were developed by considering the effect of contact time...

The asymmetric unit of the title complex, [Pb(C(8)H(5)O(4))(C(9)H(6)NO)](n), comprises a Pb(II) cation, a quinolin-8-olate anion and a 3-carb-oxy-benzoate anion. The coordination geometry of the Pb(II) atom is defined by one N and six O atoms, as well as a stereochemically active lone pair of electrons, and is based on a Ψ-dodeca-hedron. The quinolin-8-olate is chelating and the 3-carb-oxy-benz...

The identity of the predominating lead(ii) species in hyper-alkaline aqueous solution has been determined by Raman spectroscopy, and ab initio quantum chemical calculations and its structure has been determined by EXAFS. The observed and calculated Raman spectra for the [Pb(OH)3](-) complex are in agreement while they are different for two-coordinated complexes and complexes containing Pb[doubl...

Four new lead(II) or bismuth(III) selenites and a tellurite, namely, Pb(3)(TeO(3))Cl(4), Pb(3)(SeO(3))(2)Br(2), Pb(2)Cd(3)(SeO(3))(4)I(2)(H(2)O), Pb(2)Ge(SeO(3))(4) and BiFe(SeO(3))(3), have been prepared and structurally characterized by single crystal X-ray diffraction (XRD) analyses. These compounds exhibit five different types of structures. The structure of Pb(3)(TeO(3))Cl(4) features a th...

Flow injection analysis (FIA) system coupled with a computer-controlled auto-pretreatment (Auto-Pret) system (MGC Auto-Pret 018S) was newly developed for the determination of ultra-trace amounts of Pb(II) in aqueous samples. The solid phase material, Analig Pb-01 (GL Sciences), was packed in a mini-column (2 mm i.d. x 40 mm length), which was installed in the Auto-Pret system. In the mini-colum...

The N-oxide O atom of the minoxidil unit in the 1/1 adduct with lead(II) iodide, [PbI(2)(C(9)H(15)N(5)O)](n), bridges two Pb(II) atoms, as do each of the I atoms. The bridging inter-actions give rise to a linear chain motif that propagates along the a axis of the ortho-rhom-bic unit cell. The coordination sphere around the six-coordinate Pb(II) atom is a distorted ψ-monocapped octa-hedron in wh...

We have revealed the fundamental mechanism of specific Cs(+) adsorption into Prussian blue (PB) in order to develop high-performance PB-based Cs(+) adsorbents in the wake of the Fukushima nuclear accident. We compared two types of PB nanoparticles with formulae of Fe(III)4[Fe(II)(CN)6]3·xH2O (x = 10-15) (PB-1) and (NH4)0.70Fe(III)1.10[Fe(II)(CN)6]·1.7H2O (PB-2) with respect to the Cs(+) adsorpt...

In the polymeric title complex, [Pb(2)(CH(3)CO(2))(2)(C(10)H(6)O(6)S(2))](n), the acetate anion functions in a chelating mode and both O atoms also coordinate to adjacent Pb(II) atoms. The naphthalene-1,5-disulfonate dianion, which lies on a center of inversion, is connected to four Pb(II) atoms. The bridging modes of the monoanion and dianion give rise to a three-dimensional coordination polym...
