During the beam time in 2003 a carbon beam from the ECR ion source was mainly accelerated via the high charge state injector (HLI) in the UNILAC for the SIS-injection like in the years before [1]. Several UNILAC experiments used the beam with high duty factor additionally. Additionally, the ECR source was in operation for the production of various isotopes (2H, He, Ne, Mg, Ar, Ca, Cr, Zn, Xe). ...

removing of ions from different water and waste water is one of the most important of nanofiltration potential for different aims, such as softening of potable water, remove of heavy metal ions and purification of waste water to reuse. in this study nanofiltration was used to remove of the most important ions (na+, k+, ca2+, mg2+, so42-, cl-) in sugar beet press water to reuse of this stream. e...

zinc ions are present in different types of industrial effluents, being responsible for environmental pollution. biosorption is a process in which solids of natural origin are employed for binding heavy metals. it is a promising alternative method to treat heavy metal wastes mainly because of high metal binding capacity. the effect of some important parameters on sorption capacity of cyanobacte...

Background and purpose: The discharge of toxic heavy metal ions into the environment is a serious pollution problem. Heavy metal ions pose adverse toxic risks to human health at very low concentrations. The aim of this paper is the adsorption potential of chitosan (CS) in the removal of Hg(II) and Cd(II) ions from aqueous solution. Materials and Methods: This study was conducted in laboratory s...

Larrea tridentata (creosote bush) is a plant that grows abundantly in the desert environment. This desert plant has been found naturally growing in heavy-metal contaminated soils. Previous experiments showed that the inactivated biomass of creosote bush was able to adsorb Cu(II) ions from aqueous solutions. The copper-binding capacity of the bush biomass that grows in heavy-metal uncontaminated...
