In this study, isotherm studies were investigated for the removal of basic orange 2 (BO2) dye on the montmorillonite surface. Two-parameter isotherm models such as Langmir, Freundlich, and Temkin isotherms and Three-parameter isotherm models such as Sips, Toth, and Khan isotherms were calculated by non-linear analysis method. The adsorption capacity at equilibrium was calculated by adding 0.035 g of adsorbent at 10-300 mg/L concentrations to 100 mL of synthetic dyestuff solution at room temperature. According to the results obtained, it was determined that the isotherm data matched the Langmuir isotherm with a regression coefficient of 0.995 from the Two-parameter models, and the Sips isotherm with a regression coefficient of 0.998 from the Three-parameter isotherm models. In addition, according to the results of error analysis, it was determined that the lowest error value fit the HYBRID model. SNE values support the HYBRID model. KEY WORDS: Adsorption, Basic orange 2, ...

In this study, we investigated heavy metal ions as cadmium (Cd 2+), nickel (Ni 2+) and zinc (Zn 2+) removal from aqueous solutions using synthetic resin. Batch experiments on the removal efficiency of heavy metal ions at under different conditions such as initial solution pH, stirring speeds, temperatures, initial concentrations and resin dosages of synthetic wastewater solutions were carried out. The maximal exchange levels attained were as follows: 99.76% Cd 2+ , 93.66% Ni 2+ and 83.10% Zn 2+ onto Dowex HCR-S synthetic resin at 293 K, 250 mg L-1 initial metal concentration, ion exchange time of 60 min, 400 rpm stirring speed, pH: 6.0 and 2 g resin dosage. INTRODUCTION Fast industrialization has affected to rise up disposal of heavy metals into the environment. The exceeding increase in the use of the heavy metals over the past few decades has unavoidable consequence in an increased ...

Initial boron concentration of solution was selected as experimental parameter affecting energy consumption. The other parameters such as solution pH, current density and temperature of solution were kept constant during reaction time. Experiments were carried out with different initial boron concentrations ranging from 100, 250, 500 and 1000mg/L. Increasing initial boron concentration caused to increase specific conductivity of solution. Specific conductivity of solution was a important parameter on energy consumption of electrocoagulation system. The higher specific conductivity of solution caused to the lower energy consumption values. While energy consumption value was 49,87 kW-h/m3 for 100 mg/L initial boron concentration, this value was decreased to 14, 3 kW-h/m3 for 1000 mg/L initi...

In this study, electrokinetic surface properties of montmorillonite were investigated using the microelectrophoresis technique. The zeta-potential (ζ) analysis of the montmorillonite was done by streaming potential measurements as a function of salt concentration and equilibrium pH of solution. It was found that the zeta potential of the clay particles was negative for monovalent cations (KCl, LiCl, NaCl) added to solution phase. Divalent cations (CaCl2, Ca(NO3)2, Pb(NO3)2) could provide a neutral charge at just maximum concentrations. In addition, montmorillonite had a negative charge even at pH 2 and only trivalent cations (Fe(NO3)3, FeCl3) provided positive surface charge at just maximum concentration. The characterization of the montmorillonite was performed by using XRD, XRF, FTIR, SEM imagin...

In this study, the use of Bigadiç clinoptilolite (natural zeolite) as an adsorbent for removal of methyl violet dye from solutions was investigated. The dye adsorption experiments were carried out in batch mode as a function of pH (3-9), temperature (30-50 ºC), ionic strength (0-0.1 M NaCl) , clinoptilolite calcination temperature (0-200 ºC), particle size (0-45;180-425 ìm) and solid-to-solution ratio (0.1-1.5g/50 mL). The dye adsorption capacity of the clinoptilolite mineral increased with high solution pH, high temperature, high salt concentration, low particle size and low solid-to-solution ratio. Clinoptilolite mineral provided higher adsorption capacity at calcination temperature of 50 ºC. The equilibrium adsorption data fitted to the Langmuir isotherm rather than Freundlich model. The kinetic data could be explained by the pseudo second order model. Also, the kinetic data fitted to the intra particle diffusion model and this indicated that pore diffusion was rate controlling step in the applied batch process. Maximum adsorption capacity of the clinoptilolite mineral was calculated as 75.25 mg/g at pH 9.
