In order to examine the impact of admixture amount on the heavy metal solidification/stabilization effect of Magnesium Potassium Phosphate cement (MKPC), industrial dusts, iron ore tailings and slag were added into Magnesium Potassium Phosphate containing 5g/kg of heavy metals at the ratios of 0, 5...

introduction: biosorption of heavy metals can be an effective process for the removal of heavy metal ions from aqueous solutions. also, living lichens are known to accumulate metals across their surface. materials and methods: in this study, the biosorption of cadmium ions cd (ii) by the lichens acarospora strigata, lecanora muralis and caloplaca aurantia was investigated in aqueous solution in...

Escherichia coli ZinT is a metal binding protein involved in zinc homeostasis, with additional putative functions in the resistance against other metals. Herein, a method was designed and implemented to evaluate from a structural and functional viewpoint metal binding to E. coli ZinT in 96-well microtiter plates. The isolated ZinT was mixed with several metal ions and their binding ability was ...

A total of 45 genes encoding for P-type ATPases have been identified in the complete genome sequence of Arabidopsis. Thus, this plant harbors a primary transport capability not seen in any other eukaryotic organism sequenced so far. The sequences group in all five subfamilies of P-type ATPases. The most prominent subfamilies are P(1B) ATPases (heavy metal pumps; seven members), P(2A) and P(2B) ...

Many coal-fired power plants are implementing ammonia-based technologies to reduce NO(x) emissions. Excess ammonia in the flue gas often deposits on the coal fly ash. Ammonia can form complexes with many heavy metals and change the leaching characteristics of these metals. This research tends to develop a fundamental understanding of the ammonia impact on the leaching of some heavy metals, exem...

Mining operations in the Sudbury district of northern Ontario have resulted in environmental damage caused by acid rain and heavy metal pollution. Remedial liming (Ca/MgCO3) has been used in an attempt to restore the pH of the lake water and soil to natural levels. The spatial and temporal variation of metal concentrations in the annual growth rings of trees may be a useful indicator of the eff...

chelating resins based on polyacrylonitrile and diethylenetriamine (pan-dta) wereprepared through the simple reaction of polyacrylonitrile with various volume percents ofdiethylenetriamine (dta), (25, 50, 75 and 100). the prepared resins were applied to removeheavy metal ions such as cu(ii), zn(ii) and cd(ii) from aqueous solutions. the sorptionbehaviors of the resins for these metal ions were ...
