Despite being one of the main sources iron, specularite is often associated with gangue minerals such as aegirine and chlorite. Flotation separation challenging in mineral processing industry because similar surface properties specularite, aegirine, This study investigates role selective activation mechanism Pb2+ flotation chlorite using micro-flotation experiments, solution chemistry calculati...

the removal of cd2+ and pb2+ ions from wastewater using p-tert-butyl-calix[4] arene was investigated in terms of initial ph, initial concentration, adsorbent dosage, contact time and temperature. the maximum adsorption occurred at the ph value of 6. the adsorbent studied exhibits high efficiency for cd (ii)and pb (ii) adsorption and the equilibrium states could be achieved in 10 min. adsorption...

In this study, a natural low-coast, efficient, and eco- bio-sorbent plant material (Ludwigia stolonifera), with both parts of the root shoot, were studied for removal cationic metal ions, lead Pb2+ chromium Cr6+, via batch mode experiments to evaluate their maximum adsorption capacity, held comparison between used roots shoots, based on highest bio-sorption potential. Optimization parameters, s...

The RNA polymerase of influenza A virus is a host range determinant and virulence factor. In particular, the PB2 subunit of the RNA polymerase has been implicated as a crucial factor that affects cell tropism as well as virulence in animal models. These findings suggest that host factors associating with the PB2 protein may play an important role during viral replication. In order to identify h...

Adsorption desorption processes of Pb at contaminated levels in two variable charge soils were investigated. The red soil (RAR) developed on the Arenaceous rock (clayey, mixed siliceous thermic typic Dystrochrept) adsorbed more Pb2+ than the red soil (REQ) derived from the Quaternary red earths (clayey, kaolinitic thermic plinthite Aquult). The maximum adsorption values (Xm) that were obtained ...

The uncontrolled concentrations of heavy metals introduced into the water sources need an effective method for their removal. dithiocarbamate (dtc) ligands are most popular precipitating agents used removal from wastewater. Presently, two novel dtc ligands, one without methylene linker (K2L1) and other with (K2L2) were eight ions including Fe2+, Co2+, Ni2+, Cu2+, Cd2+, Ag+, Zn2+ Pb2+ aqueous so...

The removal of heavy metal ions from wastewater by ion exchange resins ( zeolite and purolite C105), was investigated. adsorption process, which is pH dependent, shows maximum at 6 7 for C105 initial concentrations 50-250 mg/l, with resin dose 0.25-3 g. capacity found to be 9.74, 9.23 9.71 mg/g Cu2+, Pb2+, Ni2+ on respectively, while the 9.64 ,8.73 9.39 respectively. 97-98% Cu2+ 92- 93% Pb2+ ze...

Three-dimensional (3D) urchin-like MnO2@poly (sodium 4-styrene sulfonate) (PSS)/poly (diallyl dimethylammonium chloride) (PDDA)/PSS particles were prepared via the layer-by-layer (LBL) assembly of polyelectrolytes for extraction Zn2+ from alkaline media. The adsorption performance on MnO2, MnO2@PSS/PDDA/PSS, and MnO2@(PSS/PDDA)3/PSS was investigated in batch experiments. MnO2@PSS/PDDA/PSS has b...

This paper addresses the analysis of hydrothermal carbonization Tetra Pak residues using diluted sulfuric acid to obtain hydrochars for cleaning water polluted by heavy metal ions. The hydrochar samples were prepared under different conditions, and a detailed study their composition, textural parameters, surface functionalities was performed. It found that dwell time wastes significantly affect...
