Crystal violet (CV) was removed from aqueous solutions using walnut shell (WS) as an adsorbent. The effect of initial ph, contact time, adsorbent level and temperature on CV adsorption, were studied in batch mode. The results indicated that both the Langmuir and the Freundlich equations effectively described the adsorption equilibrium. A pseudo second-order kinetics provided a perfect fit for t...

The effects of varying operating conditions on metals removal from aqueous solution using a novel platinum nanopartcles/Zeolite-4A adsorbent are reported in this paper. Characterization of the adsorbent showed successful production of platinum nanopartcles on Zeolite-4A using 3 Wt% platinum. The effects of operation conditions on metals removal using this adsorbent were investigated. The optima...

The potential feasibility of anionic clay hydrotalcite for removal of eriochrome black dye from aqueous solution was investigated. The effects of various experimental parameters such as contact time, pH and adsorbent dosage were investigated. The extent of eriochrome black dye removal increased with the increased in contact time, pH and amount of adsorbent used. Adsorption data was fitted to th...

This data article describes a facile method for production of an adsorbent from Tamarix hispida wasted wood and modified by lanthanum metal for fluoride ions removal from wastewater. The main characteristics of the adsorbent consist of BET surface area, functional groups, and elemental analysis is presented. The data for attenuating the pollutants from a real wastewater treatment which was prov...

In this data article, we introduce data acquired from new adsorbent, bi-metalized chitosan particle that is successfully synthesized and applied to remove the orange II dye, an azo dye, from textile wastewater. The adsorbent was meso- and macro-porous material with BET surface area of 12.69 m(2)/g and pHzpc 6.6. The simulated textile-wastewater can be significantly treated using a relatively lo...

In this study, the performance of an adsorbent coated finned tube exchanger for carbon capture was investigated numerically. The results showed that this structure has a great potential for being applied as a medium for CO2 capture by rapid indirect thermal swing adsorption. By using this structure, the recovery of 96%, and purity of 98% were achieved with a simple cycle consisting of two steps...

The effect of water vapor on the DeSOx performance regenerable CuO/SBA-15 adsorbent was investigated for different temperatures adsorption/regeneration cycles and CuO loadings. At 400 °C a significant decrease both dynamic total SO2 adsorption capacity compared to ones measured without observed. This could be related faster migration aggregation active phase, an competition between molecules si...

In this research paper, chemically activated Thuja Occidentalis leaves carbon (CATLC) is used as an adsorbent for the expulsion of Mn(II) from aqueous solution. CATLC is characterized by FTIR, SEM and EDX. The effect of pH, initial Mn(II) concentration, CATLC dosage and contact time on the adsorption performance of CATLC for Mn(II) ions are examined by batch studies. The results reveal that CAT...

This work presents a comparative study of microwave and conventional (conductive) heating for adsorbent regeneration. A binary gas mixture representative pre-dried flue from coal-fired power plants (15% v/v CO2 in N2) was passed through rotatory fixed-bed adsorption column filled with zeolite molecular sieve (13X) an activated carbon (Norit R2030CO2). The impact the two regeneration methods on ...
