Predicting protein adsorption from solution to a surface is a perennial problem in biomedicine and related fields. Despite constant attention in the literature, it is not currently possible to predict quantitatively the amount of adsorbed protein given environment, protein and surface parameters. In previous work, we presented the Biomolecular Adsorption Database, an online collection of protei...

present study deals with the adsorption of glycolic acid (ga) from aqueous solutions by using bagasse fly ash (bfa). bfa is a solid waste generated from bagasse fired boilers and can be used as an adsorbent. batch adsorption studies were carried out to evaluate the effect of various parameters like adsorbent dose, contact time, initial concentration and temperature on the removal of ga from aq...

abstractin this work, the micro powder was the product of cedar leaf (mpcl) is used as a low-cost adsorbent for the removal of pb2+ ions from aqueous solutions. bath experiments were used to determine the best adsorption conditions the adsorption percentage of pb2+ ions mpcl samples at different initial ph, contact time (tc), adsorbent dosage and temperature (t) were investigated. effective rem...

In this study, the Bohart and Adams’ model taking into account bed depth, and influent dye concentration was studied to exhibit adsorption process of textile dyes (Basic Blue 41 – BB41 and Reactive Black 5 – RB5) in glass columns using tree barks (Eucalyptus camaldulensis). Adsorption capacity coefficient values are determined using the Bohart and Adams’ bed depth service model. The model indic...

adsorption capacity of 4-chloro-2-nitrophenol (4c2np) onto nano-ti02 from aqueous solutions wasinvestigated in a batch system by considering the effects of various parameters like contact time, nano-tio2 dosage, initial ph and initial 4c2np concentration. optimum conditions for 4c2np adsorptionwere found to be initial ph z 2, nano-tio2 closer- 0.01 g and equilibrium time 1 h. the adsorptionkine...

Cerium vanadate nanoparticles (CVNPs) were used as a solid phase adsorbent for removing methylene blue (MB) from aqueous media. The nanoparticles were obtained through a direct precipitation procedure in aqueous solutions, and were characterized by X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM). The results proved the product to comprise 25-45 nm particles. Bat...

In the present study, activated bleaching earth was used as clay adsorbent for an investigation of the adsorbability and adsorption kinetics of acid dyes (i.e., acid orange 51, acid blue 9, and acid orange 10) with three different molecular sizes from aqueous solution at 25 degrees C in a batch adsorber. The rate of adsorption has been investigated under the most important process parameters (i...

Methyl orange is one dye resulted from the textile industry. The aim of this study is to test theadsorption capacity of nickel oxide nanoparticles for removing the methyl orange from aqueoussolution. The parameters studied were the effect of temperature, contact time and initial pH ofsolution. Results indicate that the removal efficiency of nickel oxide nanoparticles increases withincreasing co...

The aim of this study is to investigate the nitrate adsorption on granular ferric hydroxide (GFH). The effect of factors such as initial concentration of nitrate, pH, contact time, and adsorbent mass were determined. The study was done in laboratory–scale in which synthetic nitrate solutions in a batch reactor were placed in contact with the adsorbent to model adsorption kinetics. It was found ...

background: the rapid increase in agricultural and industrial development has made heavy metal pollution a serious environmental problem and public health threat; therefore, removal of heavy metals from water is important. the current study prepared dnph@sds@fe3o4 nanoparticles as a novel and effective adsorbent for removal of hg(ii) ions from an aqueous solution. methods: a selective adsorbent...
