Adsorption of Cd(II) ions onto polyamine-polyurea polymer modified with pyromellitic dianhydride

Özer, Çiğdem; Boysan, Füsun; İmamoğlu, Mustafa; Yıldız, Salih Zeki (DESALINATION PUBL, 2016)

In this study, polyamine-polyurea polymer was synthesized using toluendiisocyanate and polyethyleneimine. It was then modified using pyromellitic dianhydride. The polymer so obtained (PMPPP) was used for the adsorption of ...
Adsorption of Cd(II) ions onto polyamine-polyurea polymer modified with pyromellitic dianhydride

Özer, Çiğdem; Boysan, Füsun; İmamoğlu, Mustafa; Yıldız, Salih Zeki (2014)
Adsorption of Cu(II), Ni(II) and Pb(II) ions onto polyamine-polyurea polymer modified with pyromellitic dianhydride: kinetic, isotherm and thermodynamic studies

Özer, Çiğdem; Boysan, Füsun; İmamoğlu, Mustafa (DESALINATION PUBL, 2016)

In this study, a polyamine-polyurea polymer modified with pyromellitic dianhydride was used for batch adsorption of Cu(II), Ni(II), and Pb(II) ions to examine the effects of parameters such as pH, contact time, amount of ...
Adsorptive transfer of methylene blue from aqueous solutions to hazelnut husk carbon activated with potassium carbonate

Özer, Çiğdem; İmamoğlu, Mustafa (DESALINATION PUBL, 2017)

Removal of methylene blue (MB) using activated carbon prepared from hazelnut husk by potassium carbonate (HHPCAC) chemical activation was investigated batchwise. In order to optimize the process, the effect of pH, contact ...
Artificial neural networks modeling for the prediction of Pb(II) adsorption

Kiraz, Alper; Canpolat, Onur; E. F. Erkan; Özer, Çiğdem (SPRINGER, 2019)

The work presents an artificial neural network (ANN) model predicting the efficiency of Pb(II) adsorption on polyamine-polyurea polymer modified with pyromellitic dianhydride. Adsorption percentages of Pb(II) ions, as ...
Column Solid Phase Extraction of Ni(II) and Cu(II) Using Salicylaldehyde-Modified Polyamine Polyurea Resin for Their Determination by FAAS in Waters

Özer, Çiğdem; İmamoğlu, Mustafa (PERKIN-ELMER CORP, 2017)

extraction-preconcentration procedure was developed by using a salicylaldehyde modified polyamine polyurea resin as solid phase adsorbent for the determination of Ni(II) and Cu(II) ions at trace level in waters by flame ...
Efficient removal of Cd(II), Cu(II), Ni(II) and Pb(II) by polyamine-polyurea polymer modified with 2,4-dihydroxybenzaldehyde from synthetic and real wastewaters

Özer, Çiğdem; Boysan, Füsun; İmamoğlu, Mustafa (DESALINATION PUBL, 2017)

The present study reports a synthesis of novel polymeric sorbent of polyamine-polyurea polymer modified with 2,4-dihydroxybenzaldehyde (DMPPP) and analysing of its adsorption efficiency towards some metal ions including ...
Enhanced Adsorption of Hexavalent Chromium Ions on Polyamine Polyurea Polymer: Isotherm, Kinetic, Thermodynamic Studies and Batch Processing Design

Özer, Çiğdem; Boysan, Füsun; İmamoğlu, Mustafa; Yıldız, Salih Zeki (TAYLOR & FRANCIS INC, 2016)

In the present study, polyamine polyurea polymer was employed for adsorption of Cr(VI) ions from aqueous solution. Adsorption studies were carried out to examine the effects of parameters such as pH, contact time, initial ...
Ethical Approach to Fluoridation in Drinking Water Systems of UK and Turkey

Ateş, Asude; Özer, Çiğdem (SPRINGER, 2017)

The practice of adding substances to make water safe to drink and its consequential effects on human health have been a contentious matter for a long time. In this study, the addition of fluoride in drinking water was ...
Removal of methylene blue from aqueous solutions using phosphoric acid activated carbon produced from hazelnut husks

Özer, Çiğdem; İmamoğlu, Mustafa; Boysan, Füsun (TAYLOR & FRANCIS LTD, 2012)

In this study, activated carbon (HHPAAC) was prepared from hazelnut husks using phosphoric acid activation and characterized by some physicochemical analyses. Surface area and zero point charge of pH (pH(PZC)) were found ...
