One step effective removal of Congo Red in chitosan nanoparticles by encapsulation
(Pergamon-Elsevier Science Ltd, 2017)
Chitosan nanoparticles (CNPs) were prepared with ionotropic gelation between chitosan and tripolyphosphate for the removal of Congo Red. The production of chitosan nanoparticles and the dye removal process was carried out ...
Chitosan based metal-chelated copolymer nanoparticles: Laccase immobilization and phenol degradation studies
(Elsevier Sci Ltd, 2017)
Immobilization improves the stability and reusability of enzymes. In this study, laccase, which is a green biocatalyst, was immobilized onto Cu (II)-chelated chitosan nanoparticles via adsorption and successfully applied ...
Phragmites australis: An alternative biosorbent for basic dye removal
(Elsevier Science Bv, 2016)
This study is aimed at investigating the removal of methylene blue (MB) from aqueous solutions using a reed species, Phrag-mites australis as an adsorbent. P. australis was modified by means of a chemical treatment, assuring ...
Poly (methyl vinyl ether-co-maleic acid) - Pectin based hydrogel-forming systems: Gel, film, and microneedles
(Elsevier Science Bv, 2017)
Cross-linking of natural and synthetic polymers is widely explored to achieve the desired material properties (mechanical strength, drug loading capacity, swelling and erosion rates). However, the potential of polymers ...
Colorimetric Bisphenol-A Detection With a Portable Smartphone-Based Spectrometer
(Ieee-Inst Electrical Electronics Engineers Inc, 2018)
Water quality monitoring in resource-limited settings without access to a sophisticated laboratory requires the development of low cost and portable instrumentation. Herein, we propose a newly designed handheld reflection-based ...
Bioremoval of mercury (II) from aqueous solutions by Phragmites australis: Kinetic and equilibrium studies
(Taylor & Francis Inc, 2018)
In this study, the removal of mercury (II) ions from aqueous solutions by dried biomass of Phragmites australis was investigated in the batch system. The biomass was characterized by Fourier transform infrared spectroscopy ...
Fibrous polymer-grafted chitosan/clay composite beads as a carrier for immobilization of papain and its usability for mercury elimination
(Springer, 2016)
Papain, which is an industrially important enzyme, has been immobilized on fibrous polymer-modified composite beads, namely poly(methacrylic acid)-grafted chitosan/clay. Characterization studies have been done using FTIR ...
Phragmites australis as a new cellulose source: Extraction, characterization and adsorption of methylene blue
(ELSEVIER, 2020)
The aim of this study was to investigate potential use of Phragmites australis in the production of cellulose microfibrils with chemical extraction process. Characterization of the natural P. australis and extracted fibrils ...
Preparation of a novel functionalized magnetic nanobiocomposite as a carrier for protein adsorption
(TAYLOR & FRANCIS INC, 2020)
This study aims the synthesis of a novel functionalized magnetic nanocarrier based on xanthan gum biopolymer. Glycidyl methacrylate was grafted on xanthan gum chains by radical polymerization reaction using two types of ...
Investigation on phenol degradation capability of Scenedesmus regularis: influence of process parameters
(TAYLOR & FRANCIS LTD, 2020)
Phenol removal from environmental solutions has attracted much attention due to phenol's high toxicity, even at low concentrations. This study aims to reveal the phenol biodegradation capacity of Scenedesmus regularis. ...
