in this study, the batch equilibrium method was used to conduct metribuzin adsorption/desorption experiments with eight soils from different regions of iran. the results indicated that the organic carbon (oc) content, clay content, cation exchange capacity (cec), and ph had a combined effect on the metribuzin adsorption on soil. under the experimental conditions, the adsorption amount of metrib...

The first instance of an acidic aqueous biphasic system (AcABS) based on tributyltetradecyl phosphonium chloride ([P44414 ][Cl]) and an acid is here reported. This AcABS exhibits pronounced thermomorphic behavior and is shown to be applicable to the extraction of metal ions from concentrated acidic solutions. Metal ions such as cobalt(II), iron(III), platinum(IV) and nickel(II) are found to par...

In the title compound, [Ni(C13H18NO3)2(C12H8N2)], the NiII cation shows a distorted octa-hedral coordination environment. It is formed by two N atoms from the phenanthroline ligand, as well as two N and two O atoms belonging to two 2-[(2-hy-droxy-benz-yl)amino]-4-methyl-penta-noate ligands. Complex mol-ecules are connected into layers propagating along the ab plane via hydrogen bonds formed by ...

The asymmetric unit of the title compound, [Ni(H2O)6](C12H12BrN2O5S)2·H2O, contains a half hexa-aqua-nickel(II) complex cation with the NiII ion lying on an inversion center, one 5-bromo-7-[(2-hy-droxy-eth-yl)amino]-1-methyl-6-oxido-quinolin-1-ium-3-sulfonate (QAO) anion and a half lattice water mol-ecule on a twofold rotation axis. In the crystal, QAO anions are stacked in a column along the c...

plants uptake boron (b) from the soil solution, in which boron concentration is controlled by adsorption and desorption reactions on soil organic and inorganic colloids. considering the importance of aluminosilicate minerals in ion adsorption and desorption reactions in soil, in this research, b adsorption behavior on kaolinite was studied as a function of equilibrium concentration, ph, kaolini...

By Captain C. C. DAS GUPTA, m.b., Chief Medical Officer, Hossainabad Group of Tea Estates, P. O. Gopalbagan, Jalpaiguri. Ljijution ant-Colo Niii, F. J. Palmer, in his article on " The treatment of cholera by cresol" published in the Indian Medical Gazette for August 1924, mentions that he tried cresol (Sanitol) in a small but severe outbreak of baciilary dysentery with satisfactory results. In ...

The cartoon figure on the cover image is Monkey King, who a character in classical Chinese novel “Journey to West”. He has 72 polymorphic transformations. As shown cartoon, he only needs blow breath and can create lot of little monkeys. p-Terphenylene-bridged NiII porphyrin dimer, which similar gave syn- anti-doubly heptagon-fused dimers, spiro-pentagon-bridged chlorin doubly octagon-fused dime...

volumetric techniques were employed to study the adsorption of co2 on a purified multi-wall carbon nanotubes (mwnt’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 k and pressures ranging from 30 to 150 kpa. langmuir, freundlich and sips equations were used to represent the isotherms. also the parameters of these fitted isotherm models have been determined. the ...
