Molten fly ashes generated from melting treatment of municipal solid waste and automobile shredder residues are characterized as hazardous waste due to the high content of heavy metals such as Zn, Pb and Cu. In addition, the heavy metal resources could be depleted in the near future and thus, the research towards conservation of metal resources is required. In the present work, volatilization b...

industrial wastewaters are of the major sources of heavy metal pollution in the environment. in the middle east, gas and oil industry is the major source of heavy metal pollution and releases significant amounts of metals into the terrestrial and aquatic environment. in this research the capability of the common reed ( phragmitis australis ) in absorbing heavy metals cd, pb and v from the waste...

industrial activities lead to an increase in heavy metal burden in rivers. sediment and algae (spirogyra sp.) samples were collected from the shoor river to investigate their heavy metal concentrations. dry and ashed samples of algae and sediment were digested using concentrated nitric acid. heavy metals (as, fe, zn and cr) concentration measured using an icp-oes instrument (perkinelmer, usa). ...

A newly developed Smart Pouch with enclosed biomaterial (Aloe vera and coconut husk powder) has been experimented for elimination of heavy metals i.e. (Pb2+, Cu2+, Ni2+ and Zn2+) from wastewater. The effect of concentration, pH, temperature, contact duration etc. was investigated using batch experiments which resulted that the Pouch may be accepted for convenient, efficient and low-cost accumul...

In order to reducing the risk of heavy metals concentration in plant tissues which are among the edible plants by human, find the active carbon ability in heavy metals removal from Lead (Pb) and Cadmium (Cd) contaminated soils and its effect on growth and nutrient absorption of Sweet basil, this greenhouse experiment was conducted in the faculty of agriculture, Islamic Azad University, Karaj br...

This experiment was carried out to study the effect of humic acid and growth promoting bacteria on uptake of cadmium heavy metal by annual alfalfa (Medicago scutellata L.). The experiment was arranged in pot experiment conditions in Isfahan, Iran in 2011. A factorial design was used based on completely randomized block design with four replications. Experimental treatments were humic acid and g...
