Efficiency of Modified Zeolite with Cationic Surfactant Hexadecyltrimethylammonium Bromide in Removal of Diazinon from Aqueous Solutions
Background and purpose: Diazinon is one of the most widely used pesticides in agricultural pest control that pollutes water resources. The aim of this study was to evaluate the adsorption of diazinon from water by zeolite modified with cationic surfactant hexadecyltrimethyl ammonium bromide (HDTMA). Materials and methods: The amount of HDTMA surfactant used to modify the zeolite was one-fold E...
متن کاملNickel (II) Adsorption from Aqueous Solutions by Physico-Chemically Modified Sewage Sludge
This study assesses teh potential of activated carbon prepared from sewage sludge for nickel ions adsorption from aqueous solutions. Activated carbon physicochemical properties were determined. Batch adsorption experiments were performed as a function of pH solution, adsorbent dose, initial metal ions concentration, contact time and temperature. Teh experimental data were analyzed by teh La...
متن کاملAdsorption and Photocatalytic Properties of Surface-Modified TiO2 nanoparticles for Methyl Orange Removal from Aqueous Solutions
Titanium dioxide nanoparticles surface-modified by 5-sulfosalicylic acid 5-SA-TiO2 were prepared in ethanol by the chemisorption process. The effects of surface improvement on the photocatalytic degradation and adsorption of methyl orange MO were studied in a batch system by considering the various parameters, such as contact time, adsorbent dosage, pH, initial dye concentration and temperature...
متن کاملAdsorption of Ni(II) and Cd(II) from Aqueous Solutions Using Modified Rice Husk
Background and purpose: Recently, release of pollutants such as heavy metal ions to the environment becomes one of the most important problems for soil and water. The present study was conducted to introduce modified rice husk (RH) as a new low-cost adsorbent. Materials and Methods: In this study, tartaric acid modified RH (TARH), was used as an adsorbent for removal of Ni(II) and Cd(II) from w...
متن کاملAdsorption of Acid blue 92 dye on modified diatomite by nickel oxide nanoparticles in aqueous solutions
Adsorbent prepared from waste plants for the treatment of dyeing effluents have high significance in environmental sustainability. In this research, adsorption of Acid Blue 92AB 92 dye from aqueous solutions on raw and modified diatomite nickel oxide nanoparticles was studied. The effect of different operation parameters such as pH, contact time, initial dye concentration, calcinations and sorb...
