This study reports the capacities and mechanisms of live biomass of an ascomycetes strain, Aspergillus niger HM11 biomass preparations in removing a textile dye Reactive blue 140 from aqueous solution was investigated with different parameters, such as adsorbent dosage, pH, initial dye concentrations and equilibrium time. pH study and desorption profile proved that adsorption process was suppor...

A novel composite adsorbent, Silica aerogel activated carbon was synthesized by sol-gel process atambient pressure drying method. The composite was characterized by Fourier transform infraredspectroscopy (FT-IR), scanning electron microscopy (SEM), differential scanning calorimetry(DSC) and Nitrogen adsorption / desorption isotherms (BET).In the present study, the mentioned adsorbent was used m...

An agricultural waste i.e. rice husk has been used as a cheap adsorbent for the removal ofleadas a harmful heavy metal from contaminated water via adsorption. The adsorption capacity of rice husk was calculated by equilibrium models. The results showed that the adsorption process has the best accordance with Langmuir model. The kinetics of the adsorption was also investigated and obtained that ...

The aim of this work was to obtain information about interactions between polyphenols and β-glucan through linear adsorption equilibrium models. Polyphenolic compounds can interact with various food ingredients such as carbohydrates, proteins and lipids and these interactions can affect polyphenol bioactivities. Interactions can be studied through the adsorption process at a constant temperatur...

Activated carbon prepared from Euphorbia tirucalli L wood (ETAC) by chemical activation with phosphoric acid has been analysed for the removal of Reactive Red and Reactive Blue dyes from aqueous solutions through batch adsorption technique. Lower solution pH favours the adsorption of reactive dyes. The amount of dye adsorbed per unit mass of adsorbent increases with the increase in temperature ...

introduction: arsenic is known as a carcinogenic compound in drinking water . it can cause acute and chronic effects on human health. in this study, the effect of polyamidoamine dendrimer generation 3(pamam g3) as adsorbents for removal of arsenic (v) from aqueous solutions was evaluated.     methods: adsorption experiment was studied in batch system and the effect of different variables like p...

Absorptive characteristics of polyaniline synthesized in mixture of water and acetonitrile in 50/50 volume ratio was studied. Synthesized polyaniline in powder shape is used as an adsorbent to remove toxic hexavalent chromium from aqueous solutions. Experiments were conducted in batch mode with different variables such as agitation time, solution pH and initial concentration of hexavalent chrom...

This paper presents data on batch equilibrium adsorption onto the coal-based activated carbon Ž . 207EA Sutcliffe Speakman of Malachite Green, formalin, Chloramine-T and Oxytetracycline. These substances are widely used in aquaculture to control fish parasites and disease, but few data were previously available on their adsorption behaviour. In addition, equilibrium adsorption data Ž . for carb...

The soft fundamental-measure theory, which was based on the additive colloid-polymer mixture [M. Schmidt, Phys. Rev. E 62, 3799 (2000)] has been employed to investigate the adsorption of a colloid-polymer mixture within a hard slit pore. The calculated results show that the adsorption for the confined colloid-polymer mixture is very different from those of the colloid-colloid and polymer-polyme...
