Removal of Zn(II) from chloride acidic solutions with hydrophobic quaternary salts

Nitrate Removal from Aqueous Solutions Using Almond Charcoal Activated with Zinc Chloride

Background & Aims of the Study: Nitrate is one of the most important contaminants in aquatic environments that can leached to water resources from various sources such as sewage, fertilizers and decomposition of organic waste. Reduction of nitrate to nitrite in infant’s blood stream can cause “blue baby” disease in infants. The aim of this study was to evaluate the...

Removal of perilous dyes from aqueous solutions with CuO adsorbent

Benzoic Compounds Removal from Aqueous Solutions by Acidic Silk: Equilibrium and Kinetic Study

Background & Aims of the Study: p-Chloronitrobenzene is a benzoic compound that widely used in many chemical industrials. p-Chloronitrobenzene may be absorbed through the skin and is suspected to causing cancer. So, developing an easy method to remove of it from the environment is necessary. Equilibrium isotherms and adsorption kinetics of p-Chloronitrobenzene onto modified sil...

Solubility Limits of Major Salts in Sodium Chloride Solutions

The solubility limit data of salts are typically measured in distilled water and not in saline or salt-laden solutions. So, the current study was initiated to measure the solubility limit of major salts in different concentration of NaCl solutions and was compared to the solubility limit of the same salt to that in real seawater solution. A major finding from the experimental results was that t...

Synthesis of Quaternary Heterocyclic Salts

The microwave synthesis of twenty quaternary ammonium salts is described. The syntheses feature comparable yields to conventional synthetic methods reported in the current literature with reduced reaction times and the absence of solvent or minimal solvent.
