The ability of a particular banana fibre in removing reactive dyes from textile wastewater was studied in the present work. Locally available ground seeded banana fibre of ≤ 212 μ was used as adsorbent. Initially the adsorbent was tested on standard Novacron Blue FN-R reactive dye solutions and then it was also applied to raw textile wastewater. The adsorbent was found very effective to remove ...

The potential of spherical lignin beads as an adsorbent to take up Llysine from aqueous solution was investigated. The kinetic data were estimated by the pseudo-first-order and pseudo-second-order models. The mechanism of adsorption was also studied using the Boyd model and Webber’s intraparticle diffusion model. The equilibrium data were modeled by the Langmuir, Freundlich, and Dubinin-Radushk...

Hemoadsorption, or hemoperfusion (HP) was introduced by H. Yatzidis in early 1960s [1]. It is an extracorporeal technique that cleanses blood by passing it through an adsorbent column. Active carbon (AC) was the first choice due to its undisputable superiority as an adsorbent over other materials. Although the initial results were very successful, this procedure induced a series of complication...

In the present investigation, three different solid wastes namely almond green hull, eggplant hull, and moss were initially treated and used as adsorbents for the adsorption of strontium ion from aqueous solutions. Adsorbent types and chemical treatments are proved to have effective roles on the adsorption of Sr(II) ion. Among the three adsorbents, almond green hull demonstrated strong affinity...

The extraction of cellulose from sisal fiber was done initially using the steam explosion method. Extracted cellulose was grafted with acrylic acid in the presence of ceric ammonium nitrate redox initiator. The grafting phenomenon taking place between cellulose and the acrylic acid was proved by Fourier transform infrared spectroscopy (FTIR). The prepared graft copolymer was used as adsorbent f...

an adsorbent was developed from matured leaves of the aloe barbadensis miller plant for removing pb(ii) from aqueous solutions. adsorption was carried out in a batch process with several different concentrations of pb(ii) by varying amount of adsorbent, ph, agitation time and temperature. the uptake of the metal was initially very fast, but gradually slowed down indicating penetration into the ...

The Cowan I strain of the bacterium Staphylococcus aureus has been used as an adsorbent for antibodies complexed with radiolabeled antigens from cell lysates. This application is advanced as a superior alternative to other methods of immune precipitation for the isolation of antigens. It exploits the high adsorption capacity for IgG molecules by protein A molecules on the cell walls of certain ...

A hybrid adsorbent-catalytic nanostructured material consisting of aminopropyl groups and nickel nanoparticles immobilized in mesoporous silica nanoparticles (APNi-MSN) was employed to selectively capture free fatty acids (FFAs) and convert them into saturated hydrocarbons. The working principle of these sorbent-catalytic particles was initially tested in the hydrogenation of oleic acid. Beside...

Here we describe a highly porous metal-organic framework MIL-100(Fe), which is initially used as an arsenate adsorbent in water. An appropriate mesoporous size allows AsO4(3-) to enter unrestrained and then be captured successfully, furthermore resulting in the damage of long-range order of uniform mesopores. Moreover, the porous framework could also make AsO4(3-) be reversibly desorbed without...

heavy metals removal from polluted wastewater is one of the major concerns due to their harmful effectson human health and the environment. the aim of this study is to absorb cu2+ and co+2 ions from wastewater by means of a synthesized magnetite bentonite nono - adsorbent. initially, nano- adsorbent was produced by coprecipitation techniques. then, the resultant material was analyzed and evalua...
