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...

Activated carbon prepared form coconut residues (CORC), and agricultural waste byproduct obtained after oil extraction was used for the adsorption of Ni(II) form aqueous solution. The process of uptake obeys both Freundlich and Langmuir adsorption isotherms. Kinetic studies indicate that it obeys Lagergram kinetic model. Quantitative removal of Ni(II) from 100mL aqueous solution containing 10mg...

This work reports the adsorption of strontium from aqueous solutions onto PAN/zeolite composite. The strontium adsorption on the composite adsorbent was studied as a function of initial strontium concentration, pH of the solution, contact time and temperature. Adsorption isotherms like Langmuir, Freundlich, Dubinin-Radushkevich (D-R) and Temkin were used to analyze the equilibrium data at the d...

Contaminants in plating wastewater are hard to remove, especially hexavalent chromium ions. This waste stream contains a large amount of Cr6+, highly toxic metal, potential cause cancer. To reduce this pollution, sludge from supply water treatment plant (DWTS) has been used make adsorbent. was denaturized by thermal method. After that, synthetic contained Cr6+ treated batch adsorption model wit...

In this study, the removal of Pb(II) from aqueous solutions by tassel powder was studied and optimised. Batch experiments were conducted on simulated solutions using tassel powder adsorbent and the effects of contact time, pH and concentration on the extent of Pb (II) removal was studied. Equilibrium and kinetic models for Pb(II) sorption were developed by considering the effect of contact time...

The biosorption characteristics of Cd (II) ions using the living biomass of the marine diatom Phaeodactylum tricornutum were investigated. This microalga is a highly tolerant species to cadmium toxicity; for this reason, it is interesting to know its potential for use in the removal of this metal. The use of living biomass offers better possibilities than that of dead biomass since cadmium can ...

The characteristics of arsenic adsorption onto Fe-XAD8-DEHPA resin were studied on the laboratory scale using aqueous solutions and natural underground waters. Amberlite XAD8 resin was impregnated with di(2-ethylhexyl) phosphoric acid (DEHPA) via the dry method of impregnation. Fe(III) ions were loaded onto the impregnated resin by exploiting the high affinity of arsenic towards iron. The studi...

The paper presents the use of Pyrolox™ containing manganese nano oxides used for the removal of Cu(II), Zn(II), Cd(II), and Pb(II) as well as U(VI) ions. Their concentrations were analyzed using the atomic absorption spectrometer SpectrAA 240 FS (Varian) as well as UV-vis method. For this purpose the static kinetic and equilibrium studies were carried out using the batch technique. The effect o...

Unmodified montmorillonite clay was utilized as a low cost adsorbent for the removal of heavy metals from a contaminated automobile effluent. Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy were used to characterize the adsorbent. Batch sorption experiments were performed at an optimum effluent pH of 6.5, adsorbent dose of 0.1 g, particle size of 100 ...

Binding phosphate at participation of alginate/FeCl3 capsules was studied with laboratory experiments. The hydrogel microcapsules were obtained with the dropping-in method, by gelation of sodium alginate water solution by iron (III) chloride solution. Phosphate adsorption characteristics were studied in a static batch system with respect to changes in contact time, initial phosphates concentrat...
