Abstract: Waste cooking oil contains carcinogenic compounds which are formed during the frying process. The content change makes it is not worth for reuse oil. One of damages to caused by heating. quality useable refers SNI 01-3741-2013. sample used in this research waste that 5 times frying. can be improved using Nano-Montmorillonite adsorbent. results PSA and FTIR characterization show has a ...
nano-zno was employed for the adsorption of 4c2np from aqueous solutions in batch equilibriumexperiments to investigate its adsorption properties. the quantity of 4c2np adsorbed onto nano- znosurface was measured by uv-vis spectrophotometer. the effects of contact time, adsorbent dose, ph, andinitial concentration of 4c2np were investigated. the adsorption found to be strongly influenced by all...
Background and purpose: Some problems such as filtration, centrifugation, and turbidity in effluent has limited the application of activated carbon and many nano-sized adsorbents. The magnetization of adsorbents using magnetic nano-crystals (MNCs) is a useful approach to overcome these problems. In the present study, magnetic activated carbon was synthesized (since it is separated fast and easi...
MicrosoftInternetExplorer4 Background and Objectives: Nitrate is one of the most groundwater pollutants in world. Reduction of nitrate to nitrite by microorganisms cause serious health hazards. Nitrate can be eliminated using either adsorbtion or reduction. In this study, we investigated the adsorption of nitate on zeolite and the feasibility of removal improvement using supported zero v...
Preparation and Adsorption Performance of Nano-hydroxyapatite-Enhanced Acrylamide Hydrogel Adsorbent
In this study, a hydrogel adsorbent was successfully synthesized using hydroxyapatite/acrylamide/β-cyclodextrin to adsorb heavy metal ions and dyes in water. the different contents of hydroxyapatite were added hydrogel, mechanical properties adsorption material studied. Results showed that compressive strength with increased by 37.1%. The isotherm model demonstrated maximum capacity 300 mg/g. a...
Water pollution caused by thermal power plant effluent discharges has become a worrisome phenomenon due to its impact on environmental health and safety. Many treatment processes that have been used to remove heavy metals from wastewater are suffered from high cost. Chitosan is a low cost adsorbent which is biodegradable and biocompatible polymer obtained from shrimp biowaste. In the present st...
the aim of this study was to investigate the removal of toluene from air through nano-graphene modified by ionic liquid (ng-il). the batch adsorption experiments in glass bottle of gas chromatography equipped with flame ionization detector (gc-fid) were used. graphene ultrahigh-quality synthesized by substrate-free gas-phase method in a single step and graphene sheets were deposited with ionic-...
Magnetic nano-particles CuFe(2)O(4) were successful manufactured from industrial sludge by combination of acid leaching, chemical exchange, and ferrite process. For the first time these recycled nano-particles were used as adsorbent to investigate the kinetics and thermodynamics for adsorption of Cd in aqueous solutions. These experimental results showed that Cd(2+) adsorption efficiency increa...
