-electrolysis-flocculation" was used to treat lead and zinc smelting wastewater containing heavy metal ions. The influence of the experimental conditions on the removal rate of Pb2+, Zn2+, Cd2+, Cu2... of 4×10-6 (mass fraction) for flocculation reaction, under which the combined technique has the highest removal efficiency for the heavy metal ions in this wastewater. Cd2+concentration in the outlet......
and treat the organic wastewater containing heavy metal, such as Cu-EDTA solution, a novel process of Fe-C micro-electrolysis was proposed. Based on the principle of iron-carbon micro-electrolysis reaction.... So much effort has been done to study the treatment of heavy metal chelating organic wastewater using Fe-C micro- electrolysis method [20-23]. The aim of this work is to study the degradation......
Selective removal of heavy metal ions from aqueous solutions with surface functionalized silica nanoparticles by different functional groupsKONG Xiang-feng(孔祥峰)1, 2, 3, YANG Bin(杨斌)1, 3, XIONG Heng(熊...+, the 1,8-Diaminoaphalene functionalized silica nanoparticles was excellent for removal of Hg2+ at room temperature, respectively.Key words:industrial silica fume; surface functionalization; heavy metal......
’ health through food strains. Obviously, these metals’ potential ecological harm had been coming down to observed harm to the ecology. Key words: gold mining activity; soil pollution; heavy metal... physicochemical properties, namely pH and mechanical composition were also measured. The data and heavy metal concentrations have been discussed elsewhere[17]. Soil heavy metal concentrations were analyzed......
