abstract ={Background: Shortage of fluoride in water sources leads to numerous health problems. Also excess fluoride concentration is a more serious threat for health of community. Thus investigating of various physical, chemical, and biological processes for excess fluoride reduction from water supplies is considerable. This study aimed to reduce fluoride ion concentration from aqueous solutions by adsorption process by iron-coated pumice. Methods: Firstly, the pumice pieces were grinded and sized. After several preparation stages pumice particles were covered by 0.5 N iron nitrates (III) solution. Then the effect of parameters including pH (2-10), reaction time (5-120 min), initial fluoride concentration (3– 20 mg/L), and the adsorbent dose (0.1-1.5 g/L) on removal efficiency of fluoride were investigated in a batch system. Finally adsorption isotherms and kinetics models were determined. Results: The results showed that the removal of fluoride increased by increasing of reaction time and adsorbent dose, and reduced by increasing of initial fluoride concentration. The Iron coated pumice exhibited the best performance for fluoride removal (84.3%) at fluoride concentration 3 mg/L, adsorbent dose 0.5 g/L, pH= 6, and contact time 30 min. The adsorption equilibrium data fitted well with the Langmuir model (R2= 0.9989), and kinetic adsorption study showed that pseudo-second order kinetic is more favorable. Conclusion: According to results, the iron-coated pumice is an efficient, low cost and available adsorbent that can be considered for eliminating of fluoride ions from aqueous solutions.},

title = {Optimization of Coagulation Process Using Alum and Ferric Chloride for Surface Water Treatment}, 
abstract ={Background: Water scarcity and increasing demand for various applications has led to more attention to the treatment and using potential resources. Surface water is one of water resources in the societies. In the present study, the performance of two coagulants, Alum and Ferric chloride, was considered to determine turbidity, color, COD, and microbial reduction in the surface waters in Tehran. Methods: Sampling was carried out from two surface waters named Sorkhehesar and Salehabad, during summer, fall, and winter. After optimization of coagulant dosage and pH, jar test experiments were conducted, and turbidity, COD, color, and microbial changes were considered. Results: Turbidity range in Sorkhehesar and Salehabad was between 91 and 500 NTU, and 35 to 400 NTU, respectively. Optimized dose of alum for summer, fall, and winter was 45, 100, and 35 mg/L, respectively, while in case of ferric chloride the optimized dose for three studied seasons was 5, 70, and 10 mg/L. Optimized dose of alum and ferric chloride in Salehabad, was determined as 28, 115, 2 and 30, 65, and 5 mg/L. Turbidity removal efficiency using both coagulants was higher than 95 percent, and color was totally removed in all experimented conditions. Conclusion: From the stand point of turbidity, color, and COD removal both alum and ferric chloride showed the same results, however, ferric chloride dose was lower than alum. In case of turbidity removal alum showed higher removal efficiency, while for COD reduction upon the conditions, e.g. seasonal variation, alum and ferric chloride performance was not the same and was varied accordingly.},

title = {Evaluation of the Removal of 2،4 Dichlorophenol by Chitosan from Aqueous Solutions}, 
abstract ={Background: 2،4 dichlorophenol (DCP), one of the most chlorophenol compounds family with highly toxic effect, exists in agricultural areas, chlorinated waters, discharging wastewater of pulp industries and paper factories. Chlorophenols can cause damages to the kidneys, liver, pancreas and weaken the central nervous system (CNS). In the current study we would evaluate the adsorption of DCP by chitosan in aqueous environments. Materials and Methods: In this study we evaluated the effect of operational parameters such as time (15-90min), pH values (3-9), initial concentration of DCP(15-100mg/l)and the dose of chitosan (0.1-0.9g) in a batch reactor. A spectrophotometer at wavelength of 280nm was used to measure the concentration of DCP. Freundlich and Langmuir isotherm models and Pseudo-first order kinetic models and Pseudo-second-order kinetic was drawn by using of the results obtained in the absorption process. Results: Equilibrium time in the adsorbtion process was estimated to be 75 minutes (DCP Concentration- 15mg/l, Chitosan Concentration – 0.5g and pH- 6.5) with 76% removal efficiency. PH=3 was calculated as the optimal PH in absorption process (DCP Concentration- 15mg/l, Chitosan Concentration- 0.5g and Time Equilibrium-75 min) with efficiency 79% and the value of efficiency decreased by increasing PH. In 15 mg/l concentration of DCP maximum adsorption with an efficiency of 79% was observed. (Chitosan Concentration – 0.5g, Time Equilibrium -75 min and pH-3) and the maximum 87% adsorption efficiency of DCP was observed at the 0.08mg/l absorbent dose of chitosan. (DCP Concentration - 15mg/l, time equilibrium-75 min and pH=3). Adsorption process follows of Freundlich isotherm with correlation coefficient of 0.9599 and the pseudo second order kinetic model with correlation coefficient of 0.9649. Conclusion: According to results of the study, chitosan can be used to remove of DCP from industrial wastewater due to of its perfect characteristics such as biodegradability, resurgent ability, low cost and adsorption acceptable efficiency.},

title = {Removal of P-chloro Phenol from Aqueous Solutions Using Chestnut Shell Modified by Sulfuric Acid: Study of Adsorption Kinetic and Isotherm}, 
abstract ={Background: Present of p-chloro phenol in the environment due to high toxicity, mutagenic and carcinogenic effects, powerful odor production and stability in the environment caused to be categorized as priority pollutants. The aim of this study was to investigate the removal of p-chloro phenol from aqueous solution using chestnut shell modified by sulfuric acid. Methods: This study was an experimental study and chestnut shell (Quercus brantii Var. persica) was used as an adsorbent. The effects of pH, contact time, adsorbent dosage, and initial concentration on the adsorption process were evaluated, in a batch scale. The characterizations of the raw and modified adsorbent were investigated by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and X-ray diffractometer (XRD). Langmuir and Fruindlich isotherm models and pseudo-first order kinetic, pseudo-second order kinetic were evaluated by experimental data. Results: The results showed that the removal efficiency of p-chloro phenol increased with increasing of the contact time and adsorbent dosage, and had a reverse effect with increasing of pH and p-chloro phenol initial concentration. The maximum adsorption capacity of p-chloro phenol by modified chestnut shell adsorbent was achieved of 3.33 mg/g and the maximum removal efficiency of p-chloro phenol was 87 percent at pH=4. The experimental data were well descripted by Freundlich isotherm (R2>0.92) and pseudo-second order kinetic (R2>0.94). Conclusion: This study showed that the chestnut shell could be effectively used at removal of p-chloro phenol from aqueous solutions. As the chestnut shell is a waste, so it can be applied as an adsorbent for removal of pollutants such as p-chloro phenol.},
