Humic polymer complexes for purification of mineralized water

Polymer Nanocomposite Hydrogels for Water Purification

Alumina and admicellar sorbents for the separation of copper(II) ions and humic complexes in water.

alumina 1,2 or hydrated iron(III) oxide, 3 are called admicelles, whose interior tends to incorporate sparingly soluble organic constituents. Previously, we proposed a novel separation technique with admicellar sorbents for inorganic trace analysis. 4,5 For example, trace heavy metals in water were converted into hydrophobic chelates with ammonium pyrrolidinedithiocarbamate (APDC), and successf...

Safety Evaluation of Mangifera Indica Bark for Raw Water Purification

Background: Synthetic coagulants commonly used for water treatment are associated with undesirable properties, such as inefficacy and toxicity in addition to being expensive. Natural coagulants are considered safe and economical alternatives for developing countries where the plants are abundantly available. Methods: The phytochemical composition and safety of water samples treated with Mang...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

Preparation and Application of Water-soluble Polymer-metal Complexes

A series of water-soluble polymers and derivatives with chelating groups has been prepared and investigated for the complex formation with various metals. The complexation of basis polymers, such as poly(ethyleneiruine) , poly(vinylamine) , and poly(acrylic acid), as well as copolymers was carried out in homogeneous phase. Membrane filtration allowed continuous or discontinuous separation of th...
