Zeolite is widely used for removing heavy metals from aqueous solutions. The objective of this study was to assess three sizes of zeolite in removing lead, nickel and cadmium from wastewater. A splite-plot experimental design was employed with 45 treatments and three replications at Shiraz University Lab in 2011. The treatments were five different concentrations of the pollutant and three sizes...

Background and purpose: Lead is a toxic compound which causes variety of health problems in water environments. This study investigated the efficiency of Tio2/Sio2 hybrid nanoparticles in removal of lead from paint industry effluents. Materials and methods: This experimental study was done in samples of synthetic and real wastewater from Binalood paint factory within six months. The chemical q...

this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...

Bioaccumulation of heavy metals in food chains is one of the most important environmental and health problems of aquatic ecosystems. The aim of the present study was to evaluate the amount of lead metal uptake by Gammarus sp. And sedimentation took place in the coastal region of Sisangan in the Caspian Sea. In this study Gammarus sp. As the predominant benthic in soft sediments as a biological ...
