The removal kinetics and mechanism of alizarin red-s dye, adsorptions on coconut shell activated carbon [CSAC] is studied. The use of low cost ecofriendly adsorbent has been investigated as an ideal alternative to the current expensive methods of removing the dye from aqueous solution. The adsorption removal of Alizarin Red-S dye on CSAC was investigated using batch adsorption technique. The di...

Versatile odor sensors that can discriminate among huge numbers of environmental odorants are desired in many fields, including robotics, environmental monitoring, and food production. However, odor sensors comparable to an animal's nose have not yet been developed. An animal's olfactory system recognizes odor clusters with specific molecular properties and uses this combinatorial information i...

The ability of activated carbon produced from coconut shell to remoe mercury Hg (II), Lead Pb (II) and Copper Cu (II) from dye effluent was investigated. The activated carbon was produced through chemical activation processes by using zinc chloride (ZnCl2). The adsorption capacity was determined as a function of adsorbent dosage. The adsorption Isotherms of the studied metals on adsorbent were ...

BACKGROUND Removal of mercury from aqueous environment has been highly regarded in recent years and different methods have been tested for this purpose. One of the most effective ways for mercury ions (Hg(+2)) removal is the use of modified nano porous compounds. Hence, in this work a new physical modification of mesoporous silica (SBA-15) with 1, 3, 5 (Trithiane) as modifier ligand and its app...

A multi-functional polystyrene based adsorbent (NKU-9) with a unique mesoporous and a high surface area was prepared by suspension polymerization for removal of therapeutic toxins in blood purification. The adsorbent produced had an almost equal amount of mesopore distribution in the range from 2 to 50 nm. The adsorption of serum toxins with different molecular weights were examined by in vitro...

In this paper, a detailed 3D modelling of flow and coupled heat and mass transport in a channel coated with adsorbing material is presented. A comparative study between a simplified 1D model and the detailed 3D model is carried out. Both 3D and 1D predictions are compared with experimental data available from literature as well. The time-dependent variation of temperature and heat flux distribu...

BACKGROUND Aflatoxins are serious hazard to poultry industry and human health. Broiler chickens fed on aflatoxin contaminated feed develop various abnormal signs and behavior including less attraction toward feed, abnormal faeces consistency, growth retardation, dirty and ruffled feather, abnormal organs size and weight and blood serum biochemistry. Therefore the study was aimed to detoxify afl...

Nanostructured zinc oxide (ZnO) was successfully synthesized by precipitation method using the extract of Cylea barbata Miers (CBM) leaves as a soft template after 3 h of calcinations in furnace at 500oC in the open air. Characterization results showed that the nanostructured ZnO had hexagonal wurtzite structure with space group P63mc and nano-scale particle diameter. It was suggested that the ...

wileyonlinelibrary.com internal/external surface sites of the nanostructure. Thus, the big challenge is in the nanostructure architecture where all of these parameters need to be optimized simultaneously. For the case of a supercapacitor, the nanostructure material is used as the framework to store and transport charges between two parallel electrodes. A conventional supercapacitor usually cons...

a straightforward approach for the extraction of the quercetin was carried out by a nanoporous molecularly imprinted acrylic acid-based network copolymer as asolid sorbent. this technique involves a molecular template (quercetin) which is surrounded by functional monomers and are subsequently co-polymerized in the presence of an excess of the cross linkers. in this process, three-dimensional bi...
