Re-refining of waste mineral insulating oil by extraction with N-methyl-2-pyrrolidone
(Elsevier Science Bv, Amsterdam, 2006)
Extraction with N-methyl-2-pyrrolidone (NMP) via the three-stage mixer-settler operation was studied as possible process for re-refining of waste mineral insulating oil. The following extraction process parameters were ...
Removal of model cationic dye by adsorption onto poly(methacrylic acid)/zeolite hydrogel composites: Kinetics, equilibrium study and image analysis
(Elsevier, Amsterdam, 2014)
Composites based on poly(methacrylic acid) (PMAA) and two types of zeolite, hydrophilic zeolite A and hydrophobic zeolite ZSM-5, were synthesized. The obtained hydrogel composites that combine well the strong interaction ...
The potential application of TiO2/hydrogel nanocomposite for removal of various textile azo dyes
(Elsevier, Amsterdam, 2014)
TiO2/hydrogel nanocomposite has been utilized for investigation of photocatalytic degradation of three different groups of anionic azo dyes in aqueous solutions under solar light simulating source in order to evaluate its ...
