the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...

The structure of 2,3,6,7,10,11-hexahydroxytriphenylene (hhtp) methanol monosolvate, C18H12O6·CH3OH, has triclinic symmetry (space group P-1). The compound has a three-dimensional layered network structure formed by intermolecular hydrogen bonding. Structure analysis with Hirshfeld surfaces is shown to be a sensitive method for comparing π-stacking effects in the five known solvates of hhtp. The...

Recrystallization of Cs2[Mo6X14] (X=Cl, Br) was examined using typical organic solvents, i. e., methanol (CH3OH), acetone (CH3COCH3) and dichloromethane (CH2Cl2) in order to modify crystal structures optoelectronic properties by promoting purity or inducing insertion guest molecules. To this context, we performed recrystallization solvent liquid exposure vapor those solvents. Subsequent single ...

Elucidation of complex heterogeneous catalytic mechanisms at the molecular level is a challenging task due to the complex electronic structure and the topology of catalyst surfaces. Heterogeneous catalyst surfaces are often quite dynamic and readily undergo significant alterations under working conditions. Thus, monitoring the surface chemistry of heterogeneous catalysts under industrially rele...

ABSTRACT We study molecular emission in a massive condensation at the border of H ii region RCW 120, paying particular attention to Core 1 and 2 objects, most fragments found previously by ALMA. The latter fragment was suggested host high-mass analogue Class 0 young stellar object. present spectra mm range made with APEX telescope. detect CH3OH C34S lines Cores 2. CH3CN series SO2 are only esti...

The mol-ecular structure of the title complex, [Ni2(C11H13NO3)2]·CH3OH, contains two Ni(II) atoms and two doubly deprotonated 6-meth-oxy-2-{[(3-oxidoprop-yl)imino]-meth-yl}phenolate ligands. The Ni(II) atoms are each four-coordinated in a distorted square-planar geometry by three O atoms and one N atom derived from the phenolate ligands. The solvent mol-ecule is linked to the complex mol-ecule ...

In the title complex, [Mn(C20H14N2O2)Cl]·CH3OH, the central Mn(III) atom displays a distorted square-pyramidal coordination by two N and two O atoms from the tetradentate 2,2'-[1,2-phenyl-enebis(nitrilo-methanylyl-idyne)]diphenolate ligand and one chloride ligand. The Mn(III) atom is 0.525 (4) Å out of the square basal N2O2 least-squares plane. The complex mol-ecule is hydrogen bonded to the me...
