Removal of total petroleum hydrocarbons from polluted urban soils of the outskirts of Ahvaz, southwestern Iran
Earlier phases of economic expansion and urban development have resulted in significant sources of urban soil contamination. Petroleum hydrocarbons are one of the most common groups of persistent organic contaminants in the environment. In this study, two types of treatment in 3 concentrations were prepared that were included plant treated by 1% oil pollution, treatment by 1% contamination with...
متن کاملCharacteristics and mechanisms of nickel adsorption on biochars produced from wheat straw pellets and rice husk
The adsorption characteristics and mechanisms of Ni2+ on four-standard biochars produced from wheat straw pellets (WSP550, WSP700) and rice husk (RH550, RH700) at 550 and 700 °C, respectively, were investigated. The kinetic results show that the adsorption of Ni2+ on the biochars reached an equilibrium within 5 min. The increase of the solid to liquid ratio resulted in an increase of Ni2+ remov...
متن کاملRemoval of Lead from Contaminated Soils with Chelating Agents
The biodegradable chelating agents [S,S]-ethylenediaminedisuccinic acid (EDDS), citric acid and the low biodegradable chelating agent ethylenediaminetetraacetic acid (EDTA) were investigated for their applicability for the removal of lead from soil by soil washing and electrokinetic processing. In the soil washing tests at 298K, the removal efficiency of lead with EDDS and EDTA was high in the ...
متن کاملCharacterization and Pb(II) removal potential of corn straw- and municipal sludge-derived biochars
Corn straw- and municipal sludge-derived biochars (CS-BC and MS-BC, respectively) were used to remove Pb(II) from aqueous solutions. Despite being pyrolysed at the same temperature (723 K), MS-BC showed higher porosity and hydrophobicity than CS-BC. The optimum biochar loading and pH values allowing efficient Pb(II) removal (greater than 80%) were 0.2 g l-1 and 7.0, respectively. The presence o...
متن کاملBiodegradable Nanocomposites from Wheat Straw
We investigate the mechanical and thermal properties of cellulose nanofiber reinforced starch based thermoplastic composites. Cellulose nanofibers were isolated from wheat straw by a chemi-mechanical technique. Their morphology, physicochemical and thermal properties were investigated to examine potential applications as reinforcement fibers in biocomposites. Transmission electron microscopy re...
