The structure of anhydrous nickel, niobium and tantalum metal chlorides in ionic liquids IL) is important in the development of new electrochemical alloy deposition techniques. In order to understand the interactions of these metal ions with ionic liquids, we have investigated their structures in situ with X-ray Absorption Spectroscopy (XAS). The ionic liquid used in this study is 1-methyl-3-et...

Introduction: The removal of organic precursors of disinfection byproducts (DBPs), i.e. natural organic matter (NOM), prior to disinfection is considered as the most effective approach to minimise the formation of DBPs. Trihalomethanes (THMs) as the main group of DBPs are categorized and considered to have the potentiality of increasing the rate of liver, kidney and CNS adverse effects. Methods...

background: entry of untreated wastewater of wool scouring factories has been associated with many environmental hazards because of high rate of pollution. presently effective treatment methods and reducing the costs of operation and maintenance from treatment units have always been under the attention of this industry owners. the aim of this survey is to present a suitable method for the treat...

A study has been made of t he reactions of lithium aluminum hydride with methyl bromide, methylene chloride, meth ylene bromide, methylene iodide, chloroform, bromoform, and carbon t etrachloride. Except for hydrogen and unreacted h alida, essentia lly pure methane was formed in each case. The amount of hydrogen evolved increased with the n umber of halogen atoms in the molecule, reaching a max...

The transformation of methyl tert-butyl ether ~MTBE! and tert-amyl methyl ether ~TAME! using bifunctional aluminum in the presence of dioxygen ~O2! has been examined. Bifunctional aluminum, prepared by sulfating zero-valent aluminum with sulfuric acid, is an innovative extension of zero-valent metal technology. It has a dual functionality of simultaneously decomposing both reductively and oxida...

Topical solutions containing aluminum chloride are known to be the first line of therapy for hyperhidrosis. Palmar hyperhidrosis however, is less responsive to aluminum chloride therapy and successful treatment may require 6-8 h application of high concentrations up to 30% that commonly leads to skin irritation. The purpose of this study is to investigate the effect of 30 min iontophoretic appl...

The title compound, C(6)H(6)Cl(2)N(4)O(2), was prepared by the nucleophilic substitution of 2,4,6-trichloro-1,3,5-triazine by glycine methyl ester hydro-chloride, and was isolated from the reaction by using flash chromatography. The crystal structure at 150 K reveals the presence two crystallographically independent mol-ecules in the asymmetric unit which differ in the orientation of the pendan...

The synthesis of the title compound, C(21)H(18)N(2)OS, involves the reaction of 3-methyl-benzoyl chloride with potassium thio-cyanate in dry acetone followed by condensation of the 3-methyl-benzoyl isothio-cyanate with diphenyl-amine. The carbonyl [C-O = 1.215 (2) Å] and thio-carbonyl [C-S = 1.6721 (17) Å] distances indicate that these correspond to double bonds. The short C-N bonds at the cent...

phosphorus is an important nutrient for plant and microorganisms growth, thus has an important role in creating eutrophication of surface waters. the present study has investigated poly aluminum chloride efficiency on orthophosphate removal by coagulation and chemical precipitation process in municipal wastewater in west wastewater treatment plant. this bench scale study was performed on influe...
