Nano zerovalent iron (nZVI) is an effective adsorbent for removing various organic and inorganic contaminants. In this study, nZVI particles were used to investigate the removal of Cd(2+) in the concentration range of 25-450 mg L(-1). The effect of temperature on kinetics and equilibrium of cadmium sorption on nZVI particles was thoroughly examined. Consistent with an endothermic reaction, an i...
Two common waste materials, red mud and fly ash, were used to produce a new nano-hybrid adsorbent by heat treatment with alkali addition. The new zeolitic structure formation of the hybrid adsorbent was revealed using the BET surface area, XRD, and SEM analyses. This hybrid adsorbent was utilized to remove arsenic from synthetic and real waste waters by batch and column adsorption experiments. ...
Background and Aim: Agricultural poisons are one of the most important groups of pollutants in agricultural industries that cause environmental pollution. The main objective of this research was to remove imidacloprid from contaminated water by using modified magnetic-silica core-shell nanoparticles. Materials and Methods: This study was conducted at the laboratory scale and batch system. The ...
On-line solid phase extraction (SPE) based on nano adsorbent for pre-concentration of inorganic arsenic in water and waste water samples was developed prior to determine by hydride generation atomic absorption spectrometry (HG-AAS). By hydride generation simulation system (HGSS), the inorganic arsenic in liquid samples changed to hydride form and pass through nano platinum multi wall carbon n...
Abstract The adsorption of CO 2 on a nano-calcium oxide (nano-CaO) adsorbent was investigated under different conditions temperature and supply pressure, considering kinetic, isotherm, thermodynamic parameters. CaO is crystalline material with high surface area nanosized particles porosity, which showed rapid initial rates in the moderate range studied. well described by pseudo-second-order int...
Green Synthesis of Nano-Zero-Valent Copper for the D-Blue 60 Textile Dye Removal from Aqueous Medium
Abstract Green synthesis of zero-valent copper nanoparticles successfully performed using Ficus benjamina leaves. The novel adsorbent nano-zero-valent (FB-nZVCu) characterized by utilizing scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FT-IR). size these typically ranges from 16 to 18 nm. This investigated for removal D-blue 60 textile wastewater. impact differ...
in order to investigate the gas separation ability of a column packed with nanozeolitic material, nano nay zeolite was synthesized and granulated. these uniform granules packed in a chromatographic column were utilized for separation of xe and kr under various operating conditions. with regards to the response peaks obtained from trace injections of xe and kr into the column, the first and seco...
Palygorskite clay has been investigated as low cost and ecofriendly adsorbent for the removal Basic Red 2(BR-2) from aqueous solution. Batch adsorption studies are carried out by observing effect of amount of adsorbent dose, contact time, pH, initial concentration of ( BR-2) and particle size of adsorbent on the adsorption capacity of the adsorbent were studied. Adsorption data fits the Langmui...
