The aim of this study was to investigate the removal of Escherichia coli and heavy metals (Pb, Cd 2+ and Zn ) from wastewater using silver-modified clinoptilolite under different experimental conditions through the combined disinfection of pathogenic microorganisms by the silver ions and sorption of heavy metals on clinoptilolite. Batch experiments were conducted to look at the effects of initi...

blood pressure, reproductive abnormalities, developmental defects, abnormal vitamin D metabolism, and in Reactions of heavy metals with soil are important in determining some situations death (Hrudey et al., 1995; USEPA, metal fates in the environment. Sorption characteristics of two heavy metals, Cd and Pb, in three tropical soils (Mollisol, Oxisol, and Ultisol) 1992). from Puerto Rico were as...

Salvinia exhibit capacity for removing contaminants such as heavy metals, inorganic nutrients, explosives from wastewaters. Properties such as high productivity, high sorption capacity and high metal removal potential establish Salvinia as an aquatic fern with immense potential for use in phytoremediation technologies. Realizing capabilities of Salvinia, its role for mass scale use in phytoreme...

industrial processes release a range of gaseous and particulate pollutants containing heavy metals into the air. lack of enough attention to the design, installation, repair and maintenance of gas and dust filtration systems in industries, is one of reasons of increasing the emissions of these pollutants. hereon, the steel making processes is one of emission sources of heavy metals. according t...

As a novel family of 2D materials, MXenes provide an extensive variety applications in water and effluent treatment due to their distinctive properties attractive applicability, including superior electrical conductivity, higher thermal stability, hydrophilicity, high sorption-reduction capacity. Their excellent sorption selectivity makes them perfect for removing hazardous contaminants. Curren...

Tree bark is among the widely available and low-cost sorbents for metal adsorption in aqueous environments. A state-of-the-art review is compiled carrying out a comprehensive literature search on the biosorption of heavy metals in solution onto different bark species, including a characterization of bark structure and chemistry. The results indicate that biosorption has been gaining importance ...

There is a continual influx of heavy metal contaminants and pollutants into the biosphere from both natural and anthropogenic sources. A complex variety of abiotic and biotic processes affects their speciation and distribution, including adsorption onto and desorption from mineral surfaces, incorporation in precipitates or coprecipitates, release through the dissolution of minerals, and interac...

Background: Contamination of the environment due to heavy metals is a major concern to human life and the environment. This study was conducted to investigate and quantify the copper and zinc concentrations in industrial estates soil in Arak, Iran. Methods: Four industrial estates were considered for the experimental design, including Arak 1, Arak 2, Arak 3, and Ghotbe Sanaati. For prelimin...
