Modification of Sargassum angustifolium by molybdate during a facile cultivation for high-rate phosphate removal from wastewater: structural characterization and adsorptive behavior
In this paper, a new and facile approach for molybdate loading in the brown algae of Sargassum angustifolium is introduced. The molybdate ions were entered into the algae body during a short cultivation to produce algae-Mo as a novel adsorbent for eliminating phosphate ions from synthetic and real wastewaters. Results of the surface analysis showed that molybdate loading onto the algae was succ...
متن کاملAdsorptive removal of phosphate from wastewater using mesoporous titanium oxide
The adsorption of phosphate onto mesoporous TiO2 was investigated in order to reduce phosphorus concentrations in wastewater and provide a potential mode of phosphorus recovery. Three equilibrium isotherms were used to optimize and properly describe phosphate adsorption (R > 0.95). The maximum capacity of phosphate on the adsorbent was found to be 50.4 mg/g, which indicated that mesoporous TiO2...
متن کاملModification of 13X Molecular Sieve by Chitosan for Adsorptive Removal of Cadmium from Simulated Wastewater
Chitosan was used to modify a 13X molecular sieve to improve its cadmium removal capability. After being modified with 2% chitosan-acetate for 2 h at 30 °C, significant uptake of Cd2+ could be achieved. The uptake of Cd2+ on the modified 13X molecular sieve followed the Langmuir isotherms with a capacity of 1 mg/g. The kinetics of Cd2+ removal by modified 13X molecular sieve followed a pseudo s...
متن کاملPhosphate and nitrate removal from municipal wastewater by algae Scenedesmus obliquus cultivation and production of algal biomass
Nitrate and phosphate are abundant in urban wastewater. We evaluated the efficiency of nitrate and phosphate removal from wastewater by Scenedesmus obliquus and its use as a medium for Scenedesmus obliquus. Samples were collected from the effluent of central wastewater treatment in Gorgan. This experiment was done by 3 treatments and 6 replications that effluent with 100%, 50% and 0% were dilut...
متن کاملPolysulfone/Iron Oxide Nanoparticles Ultrafltration Membrane for Adsorptive Removal of Phosphate from Aqueous Solution
Excessive nutrient contents in water bodies renders eutrophication and causes undesired structural changes to the environment. One of the most straightforward strategies to address eutrophication issue is through the removal of nutrients such as phosphate ions from the water sources. A combination of membrane fltration and adsorption process is an attractive alternative...
