A variety of adsorbents are available naturallyrice husk, neem bark, clays etc. that can be used to remove dye from the discharged waste. In this study,the use of lowcost, locally available, eco-friendly and highly efficient adsorbent has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. The removal of the textile dye Methylene blue (MB...

The efficiency of activated parthenium hysterophorous as an adsorbent for removing Pesticide mixture from water has been studied. Batch mode adsorption experiments have been conducted by varying pH, concentration, adsorbent dose and contact time. Pesticide removal was pH-dependent and found to be maximum at pH 2.0. The maximum removal of pesticides was achieved within 100 min after the start of...

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...

Peanut hull, an agricultural waste, proved to act as an efficient adsorbent for five anionic and cationic dyes. The process was found to be a pH dependent, suggesting the adsorption is controlled by interaction between the charged dye molecule and the surface charge on the adsorbent. The effect of variable parameters (contact time, pH, mass of adsorbent, dye concentration, agitation and activat...

In this research we have studied aimed to compare the adsorption of dexamethasone by two adsorbent; multi-wall carbon nanotube and activated carbon with the help of UV/VIS spectrophotometer Jenway 6505 model. Adsorption chart based on the wavelength of dexamethasone has been obtained and the relevant graph is plotted by considering factor of concentration. Four different concentrations necessar...

Rhizomucor tauricus is used in the production of lipase, after several cycles it is disposed off as biological waste. A new biosorbent material fungus, Rhizomucor tauricus was immobilized, used as an adsorbent for removal of Nickel (II) and for optimization Box-Behnken design used by statistica 6.0. The time required to reach equilibrium was found to be 4 hours. The optimized concentration is 6...
