Bifunctional composite from spent “Cyprus coffee” for tetracycline removal and phenol degradation: Solar-Fenton process and artificial neural network

Oladipo, Akeem Adeyemi; Ali Abureesh, Mosab; Gazi, Mustafa (Elsevier, 2015-08-28)

Removals of tetracycline and photocatalytic degradation of phenol by Fe3O4/coffee residue (MCC) were investigated. Brunauer–Emmett–Teller (BET), vibrating sample magnetometer (VSM) and Boehm titration were employed to ...
Efficient Removal of Anionic and Cationic Dyes from an Aqueous Solution Using Pullulan-graft-Polyacrylamide Porous Hydrogel

Saber-Samandari, Samaneh; Gülcan, Hayrettin Ozan; Saber-Samandari, Saeed; Gazi, Mustafa (Springer Verlag (Germany), 2014-10-24)

A pullulan-graft-polyacrylamide porous hydrogel was prepared by radical polymerization in the presence of a crosslinking agent (N,N′-methylenebisacrylamide). Then, the swelling behavior of the hydrogel and the kinetics of ...
Facile synthesis of glucose-sensitive chitosan–poly(vinyl alcohol) hydrogel: Drug release optimization and swelling properties

Abureesh, Mosab Ali; Oladipo, Akeem Adeyemi; Gazi, Mustafa (Elsevier, 2015-05-06)

The study describes the development of glucose-sensitive hydrogel and optimization of bovine serum albumin release profile from the hydrogel. To enhance the glucose sensitivity and improve the swelling behaviors ofthe ...
Fixed-bed column sorption of borate onto pomegranate seed powder-PVA beads: a response surface methodology approach

Oladipo, Akeem Adeyemi; Gazi, Mustafa (Taylor & Francis, 2014-12-17)

Pomegranate seed powder (PS) was functionalized with polyvinyl alcohol (PVA) and utilized for boron removal from the aqueous system. Results of Brunauer--Emmett--Teller (BET) surface area analysis and Boehm titration ...
Microwaves initiated synthesis of activated carbon-based composite hydrogel for simultaneous removal of copper(II) ions and direct red 80 dye: A multi-component adsorption system

Oladipo, Akeem Adeyemi; Gazi, Mustafa (Elsevier, 2015-02)

We present a novel microwave initiated preparation of polyacrylamide/activated carbon hydrogel (PAAm-FAc) in this article and characterized by FT-IR, pHzpc and Boehm titration. The adsorbent was assessed for competitive ...
Pullulan based porous semi-IPN hydrogel: Synthesis, characterization and its application in the removal of mercury from aqueous solution

Saber-Samandari, Samaneh; Gazi, Mustafa (Elsevier, 2015-06)

A pullulan-graft-polyacrylamide semi-IPN hydrogel was prepared by free radical polymerization and became porous by the incorporation of calcium carbonate and a subsequent acid treatment. The product was characterized by ...
Single and binary adsorption of azo and anthraquinone dyes by chitosan-based hydrogel: Selectivity factor and Box-Behnken process design

Oladipo, Akeem Adeyemi; Gazi, Mustafa; Yilmaz, Elvan (Elsevier, 2015-12)

Comparative removal of two cationic dyes, Basic Green 4 (BG4) and Basic Yellow 28 (BY28), by chemically modified nanoclay was optimized using the central composite design. The chemically modified nanoclay was characterized ...
Two-stage batch sorber design and optimization of biosorption conditions by Taguchi methodology for the removal of acid red 25 onto magnetic biomass

Oladipo, Akeem Adeyemi; Gazi, Mustafa (Springer Verlag (Germany), 2015-09)

Biomagnetic material (MFC) was synthesized via simple co-precipitation and used as biosorbent for the removal of acid red 25 (AR25) under optimized conditions. The characteristics of MFC were studied using X-ray diffraction ...
Uptake of Ni2+ and rhodamine B by nanohydroxyapatite/alginate composite beads: batch and continuous-flow systems

Oladipo, Akeem Adeyemi; Gazi, Mustafa (Taylor & Francis, 2015-12-07)

Alginate encapsulated nano-hydroxyapatite beads were synthesized and characterized by Fourier transform infrared spectroscopy, Brunauer Emmett Teller surface analysis, and X-ray diffraction. Their adsorptive potential for ...
