Magnetically modified activated carbon, which synthesized by nanomagnetic iron oxide, was used for fast and effective removal of Crystal Violet from aqueous solutions. The scanning electron microscopy (SEM) images of nano-adsorbent showed that the average sizes of adsorbent are less than 100 nm. The various parameters, affecting on adsorption process, were examined including pH and temperature ...

Activated carbon derived from biomass waste, namely palm shell, was evaluated as a potential adsorbent for the removal of Reactive Black 5 dye (RB5) from an aqueous solution. This work focused on the equilibrium isotherms and the kinetics of the adsorption process. Batch adsorption tests were conducted to determine the effects of various parameters, such as contact time, RB5 concentration, adso...

OBJECTIVES Acute-on-chronic liver failure is associated with numerous consecutive organ failures and a high short-term mortality rate. Molecular adsorbent recirculating system therapy has demonstrated beneficial effects on the distinct symptoms, but the associated mortality data remain controversial. DESIGN Retrospective analysis of acute-on-chronic liver failure patients receiving either sta...

Calcium oxide (CaO) as carbon dioxide (CO2) adsorbent at the elevated temperature has been very well-received thus far. The CaO can be synthesized from natural calcium carbonate (CaCO3) sources through the reversible calcination-carbonation process. In the study, cockle shell has been selected as CaO precursors. The objectives of the study are to investigate the performance of calcination and c...

A unique combination of adsorption and electrochemical regeneration with a proprietary adsorbent material called Nyex 100 was introduced at the University of Manchester for waste water treatment applications. Nyex 100 is based on graphite intercalation compound. It is non porous and electrically conducing adsorbent material. This material exhibited very small BET surface area i.e. 2.75 mg, in c...

A low cost adsorbent Fly Ash was used for the removal of Reactive Red 194 dye (RR 194 dye) from textile effluent. The Fly ash was activated by chemical treatment by N/2 H2SO4. Batch adsorption experiments were performed as functions of adsorbent doses, initial dye concentration, contact time, and pH. The percentage of colour removal was increased with decreasing dye concentration and increasing...

Background & Aims of the Study: Since the chromium (VI) is a toxic, carcinogenic and non-biodegradable element and can accumulate in the tissues, the presence and release of this element through the effluents is associated with dangerous effects on life cycle. Thus, it should be removed from the effluents. In the present study, biosorption of Cr(VI) from aqueous solutio...

A study was carried out to find out efficiency of rice bran in removal of heavy metals such as lead and cadmium from bisolute system. The different experimental conditions such as temperature, adsorbent amount, adsorbent particle size and concentration were studied. The results showed that 100% removal was achieved for both lead and cadmium by using rice bran at 300C, contact time 100-140 minut...

The objective of this work is to study the removal of methylene blue dye from aqueous solution using low cost adsorbent obtained from the leaves of Andrographis paniculata. Batch adsorption studies were carried out by observing the effects of various experimental parameters, such as dye concentration, contact time, adsorbent dose, effect of temperature and pH. The data were fitted into the Lang...
