This paper presents the adsorption of crystal violet (CV+) from aqueous solution on surfactant-modified dolomite. Liquid phase batch operations were carried out to observe the effect of various experimental parameters such as initial dye concentration, adsorbent dosage, pH and NaCl concentration. The optimum conditions for these parameters were calculated by Taguchi method. Equilibrium isotherm...

The biosorption performance of Phlomis cancellata Bunge as inexpensive, abundant and easily available adsorbent for safranin cationic dye removal from aqueous system has been evaluated in a batch process, using response surface methodology and employing a central composite design Experimental. The influence of different parameters such as, pH, contact time, agitation rate and sorbent dosage on ...

Nickel and cadmium usually enter the environment and water resources through wastewater, released by various industries, and may have adverse effects. The current study employs α–Fe2O3 nanoparticles of 20-40 nm in order to remove nickel and cadmium from the wastewater of Saba Battery Company. Also, it investigates the influence of effective parameters on adsorption process, including pH, contac...

The adsorption studies of phenol from aqueous solution on allium sativum peel have been studied in the range of 50-250 mg/L initial phenol concentration .The study was carried out as function of contact time, pH, initial phenol concentration,allium sativum Linn peel dosage and temperature. The experiment demonstrated the maximum phenol was obtained at in pH of 2 and it takes 6h to attain equili...

In this research, the zeolite sodalite, as an inorganic ion exchange material, was chemically produced in the template-free synthesis and evaluated in order to facilitate the sorption of strontium ions from aqueous solutions in batch operations onto acid treated zeolite with dilute H2SO4 solutions. The following indicates what the batch experiments included: a sorbent amount of 0.25 g in 100 mL...

Adsorption Kinetics describes the rate at which solute is adsorbed and resident time of adsorbates on solid-liquid interface. isotherms play important role in determining interaction between adsorbate adsorbent optimum adsorption capacity adsorbent. This article considered selected kinetics models. Pseudo first order, second Elovich, Bhattacharya Venkobachar, Natarajan Khalaf were reviewed assu...

Assessment of adsorption zinc (II) ions from aqueous solution using alginate-SBA-15 sorbent nanocomposite was investigated as a function of zinc concentration, solution pH, and contact time. For that purpose, the alginate-SBA-15 nanocomposite adsorbent was prepared through encapsulation method by immobilization mesoporous SBA-15 into a polymeric matrix. Identification of functional groups and s...
